2. License Grants and Conditions
|
||||
|
||||
2.1. Grants
|
||||
|
||||
Each Contributor hereby grants You a world-wide, royalty-free,
|
||||
non-exclusive license:
|
||||
|
||||
a. under intellectual property rights (other than patent or trademark)
|
||||
Licensable by such Contributor to use, reproduce, make available,
|
||||
modify, display, perform, distribute, and otherwise exploit its
|
||||
Contributions, either on an unmodified basis, with Modifications, or as
|
||||
part of a Larger Work; and
|
||||
|
||||
b. under Patent Claims of such Contributor to make, use, sell, offer for
|
||||
sale, have made, import, and otherwise transfer either its Contributions
|
||||
or its Contributor Version.
|
||||
|
||||
2.2. Effective Date
|
||||
|
||||
The licenses granted in Section 2.1 with respect to any Contribution become
|
||||
effective for each Contribution on the date the Contributor first distributes
|
||||
such Contribution.
|
||||
|
||||
2.3. Limitations on Grant Scope
|
||||
|
||||
The licenses granted in this Section 2 are the only rights granted under this
|
||||
License. No additional rights or licenses will be implied from the distribution
|
||||
or licensing of Covered Software under this License. Notwithstanding Section
|
||||
2.1(b) above, no patent license is granted by a Contributor:
|
||||
|
||||
a. for any code that a Contributor has removed from Covered Software; or
|
||||
|
||||
b. for infringements caused by: (i) Your and any other third party’s
|
||||
modifications of Covered Software, or (ii) the combination of its
|
||||
Contributions with other software (except as part of its Contributor
|
||||
Version); or
|
||||
|
||||
c. under Patent Claims infringed by Covered Software in the absence of its
|
||||
Contributions.
|
||||
|
||||
This License does not grant any rights in the trademarks, service marks, or
|
||||
logos of any Contributor (except as may be necessary to comply with the
|
||||
notice requirements in Section 3.4).
|
||||
|
||||
2.4. Subsequent Licenses
|
||||
|
||||
No Contributor makes additional grants as a result of Your choice to
|
||||
distribute the Covered Software under a subsequent version of this License
|
||||
(see Section 10.2) or under the terms of a Secondary License (if permitted
|
||||
under the terms of Section 3.3).
|
||||
|
||||
2.5. Representation
|
||||
|
||||
Each Contributor represents that the Contributor believes its Contributions
|
||||
are its original creation(s) or it has sufficient rights to grant the
|
||||
rights to its Contributions conveyed by this License.
|
||||
|
||||
2.6. Fair Use
|
||||
|
||||
This License is not intended to limit any rights You have under applicable
|
||||
copyright doctrines of fair use, fair dealing, or other equivalents.
|
||||
|
||||
2.7. Conditions
|
||||
|
||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
|
||||
Section 2.1.
|
||||
|
||||
|
||||
3. Responsibilities
|
||||
|
||||
3.1. Distribution of Source Form
|
||||
|
||||
All distribution of Covered Software in Source Code Form, including any
|
||||
Modifications that You create or to which You contribute, must be under the
|
||||
terms of this License. You must inform recipients that the Source Code Form
|
||||
of the Covered Software is governed by the terms of this License, and how
|
||||
they can obtain a copy of this License. You may not attempt to alter or
|
||||
restrict the recipients’ rights in the Source Code Form.
|
||||
|
||||
3.2. Distribution of Executable Form
|
||||
|
||||
If You distribute Covered Software in Executable Form then:
|
||||
|
||||
a. such Covered Software must also be made available in Source Code Form,
|
||||
as described in Section 3.1, and You must inform recipients of the
|
||||
Executable Form how they can obtain a copy of such Source Code Form by
|
||||
reasonable means in a timely manner, at a charge no more than the cost
|
||||
of distribution to the recipient; and
|
||||
|
||||
b. You may distribute such Executable Form under the terms of this License,
|
||||
or sublicense it under different terms, provided that the license for
|
||||
the Executable Form does not attempt to limit or alter the recipients’
|
||||
rights in the Source Code Form under this License.
|
||||
|
||||
3.3. Distribution of a Larger Work
|
||||
|
||||
You may create and distribute a Larger Work under terms of Your choice,
|
||||
provided that You also comply with the requirements of this License for the
|
||||
Covered Software. If the Larger Work is a combination of Covered Software
|
||||
with a work governed by one or more Secondary Licenses, and the Covered
|
||||
Software is not Incompatible With Secondary Licenses, this License permits
|
||||
You to additionally distribute such Covered Software under the terms of
|
||||
such Secondary License(s), so that the recipient of the Larger Work may, at
|
||||
their option, further distribute the Covered Software under the terms of
|
||||
either this License or such Secondary License(s).
|
||||
|
||||
3.4. Notices
|
||||
|
||||
You may not remove or alter the substance of any license notices (including
|
||||
copyright notices, patent notices, disclaimers of warranty, or limitations
|
||||
of liability) contained within the Source Code Form of the Covered
|
||||
Software, except that You may alter any license notices to the extent
|
||||
required to remedy known factual inaccuracies.
|
||||
|
||||
3.5. Application of Additional Terms
|
||||
|
||||
You may choose to offer, and to charge a fee for, warranty, support,
|
||||
indemnity or liability obligations to one or more recipients of Covered
|
||||
Software. However, You may do so only on Your own behalf, and not on behalf
|
||||
of any Contributor. You must make it absolutely clear that any such
|
||||
warranty, support, indemnity, or liability obligation is offered by You
|
||||
alone, and You hereby agree to indemnify every Contributor for any
|
||||
liability incurred by such Contributor as a result of warranty, support,
|
||||
indemnity or liability terms You offer. You may include additional
|
||||
disclaimers of warranty and limitations of liability specific to any
|
||||
jurisdiction.
|
||||
|
||||
4. Inability to Comply Due to Statute or Regulation
|
||||
|
||||
If it is impossible for You to comply with any of the terms of this License
|
||||
with respect to some or all of the Covered Software due to statute, judicial
|
||||
order, or regulation then You must: (a) comply with the terms of this License
|
||||
to the maximum extent possible; and (b) describe the limitations and the code
|
||||
they affect. Such description must be placed in a text file included with all
|
||||
distributions of the Covered Software under this License. Except to the
|
||||
extent prohibited by statute or regulation, such description must be
|
||||
sufficiently detailed for a recipient of ordinary skill to be able to
|
||||
understand it.
|
||||
|
||||
5. Termination
|
||||
|
||||
5.1. The rights granted under this License will terminate automatically if You
|
||||
fail to comply with any of its terms. However, if You become compliant,
|
||||
then the rights granted under this License from a particular Contributor
|
||||
are reinstated (a) provisionally, unless and until such Contributor
|
||||
explicitly and finally terminates Your grants, and (b) on an ongoing basis,
|
||||
if such Contributor fails to notify You of the non-compliance by some
|
||||
reasonable means prior to 60 days after You have come back into compliance.
|
||||
Moreover, Your grants from a particular Contributor are reinstated on an
|
||||
ongoing basis if such Contributor notifies You of the non-compliance by
|
||||
some reasonable means, this is the first time You have received notice of
|
||||
non-compliance with this License from such Contributor, and You become
|
||||
compliant prior to 30 days after Your receipt of the notice.
|
||||
|
||||
5.2. If You initiate litigation against any entity by asserting a patent
|
||||
infringement claim (excluding declaratory judgment actions, counter-claims,
|
||||
and cross-claims) alleging that a Contributor Version directly or
|
||||
indirectly infringes any patent, then the rights granted to You by any and
|
||||
all Contributors for the Covered Software under Section 2.1 of this License
|
||||
shall terminate.
|
||||
|
||||
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
|
||||
license agreements (excluding distributors and resellers) which have been
|
||||
validly granted by You or Your distributors under this License prior to
|
||||
termination shall survive termination.
|
||||
|
||||
6. Disclaimer of Warranty
|
||||
|
||||
Covered Software is provided under this License on an “as is” basis, without
|
||||
warranty of any kind, either expressed, implied, or statutory, including,
|
||||
without limitation, warranties that the Covered Software is free of defects,
|
||||
merchantable, fit for a particular purpose or non-infringing. The entire
|
||||
risk as to the quality and performance of the Covered Software is with You.
|
||||
Should any Covered Software prove defective in any respect, You (not any
|
||||
Contributor) assume the cost of any necessary servicing, repair, or
|
||||
correction. This disclaimer of warranty constitutes an essential part of this
|
||||
License. No use of any Covered Software is authorized under this License
|
||||
except under this disclaimer.
|
||||
|
||||
7. Limitation of Liability
|
||||
|
||||
Under no circumstances and under no legal theory, whether tort (including

|
||||
|
||||
[circleci]: https://circleci.com/gh/hashicorp/go-getter/tree/master
|
||||
[godocs]: http://godoc.org/github.com/hashicorp/go-getter
|
||||
[appveyor]: https://ci.appveyor.com/project/hashicorp/go-getter/branch/master
|
||||
|
||||
go-getter is a library for Go (golang) for downloading files or directories
|
||||
from various sources using a URL as the primary form of input.
|
||||
|
||||
The power of this library is being flexible in being able to download
|
||||
from a number of different sources (file paths, Git, HTTP, Mercurial, etc.)
|
||||
using a single string as input. This removes the burden of knowing how to
|
||||
download from a variety of sources from the implementer.
|
||||
|
||||
The concept of a _detector_ automatically turns invalid URLs into proper
|
||||
URLs. For example: "github.com/hashicorp/go-getter" would turn into a
|
||||
Git URL. Or "./foo" would turn into a file URL. These are extensible.
|
||||
|
||||
This library is used by [Terraform](https://terraform.io) for
|
||||
downloading modules and [Nomad](https://nomadproject.io) for downloading
|
||||
binaries.
|
||||
|
||||
## Installation and Usage
|
||||
|
||||
Package documentation can be found on
|
||||
[GoDoc](http://godoc.org/github.com/hashicorp/go-getter).
|
||||
|
||||
Installation can be done with a normal `go get`:
|
||||
|
||||
```
|
||||
$ go get github.com/hashicorp/go-getter
|
||||
```
|
||||
|
||||
go-getter also has a command you can use to test URL strings:
|
||||
|
||||
```
|
||||
$ go install github.com/hashicorp/go-getter/cmd/go-getter
|
||||
...
|
||||
|
||||
$ go-getter github.com/foo/bar ./foo
|
||||
...
|
||||
```
|
||||
|
||||
The command is useful for verifying URL structures.
|
||||
|
||||
## URL Format
|
||||
|
||||
go-getter uses a single string URL as input to download from a variety of
|
||||
protocols. go-getter has various "tricks" with this URL to do certain things.
|
||||
This section documents the URL format.
|
||||
|
||||
### Supported Protocols and Detectors
|
||||
|
||||
**Protocols** are used to download files/directories using a specific
|
||||
mechanism. Example protocols are Git and HTTP.
|
||||
|
||||
**Detectors** are used to transform a valid or invalid URL into another
|
||||
URL if it matches a certain pattern. Example: "github.com/user/repo" is
|
||||
automatically transformed into a fully valid Git URL. This allows go-getter
|
||||
to be very user friendly.
|
||||
|
||||
go-getter out of the box supports the following protocols. Additional protocols
|
||||
can be augmented at runtime by implementing the `Getter` interface.
|
||||
|
||||
* Local files
|
||||
* Git
|
||||
* Mercurial
|
||||
* HTTP
|
||||
* Amazon S3
|
||||
* Google GCP
|
||||
|
||||
In addition to the above protocols, go-getter has what are called "detectors."
|
||||
These take a URL and attempt to automatically choose the best protocol for
|
||||
it, which might involve even changing the protocol. The following detection
|
||||
is built-in by default:
|
||||
|
||||
* File paths such as "./foo" are automatically changed to absolute
|
||||
file URLs.
|
||||
* GitHub URLs, such as "github.com/mitchellh/vagrant" are automatically
|
||||
changed to Git protocol over HTTP.
|
||||
* BitBucket URLs, such as "bitbucket.org/mitchellh/vagrant" are automatically
|
||||
changed to a Git or mercurial protocol using the BitBucket API.
|
||||
|
||||
### Forced Protocol
|
||||
|
||||
In some cases, the protocol to use is ambiguous depending on the source
|
||||
URL. For example, "http://github.com/mitchellh/vagrant.git" could reference
|
||||
an HTTP URL or a Git URL. Forced protocol syntax is used to disambiguate this
|
||||
URL.
|
||||
|
||||
Forced protocol can be done by prefixing the URL with the protocol followed
|
||||
by double colons. For example: `git::http://github.com/mitchellh/vagrant.git`
|
||||
would download the given HTTP URL using the Git protocol.
|
||||
|
||||
Forced protocols will also override any detectors.
|
||||
|
||||
In the absence of a forced protocol, detectors may be run on the URL, transforming
|
||||
the protocol anyways. The above example would've used the Git protocol either
|
||||
way since the Git detector would've detected it was a GitHub URL.
|
||||
|
||||
### Protocol-Specific Options
|
||||
|
||||
Each protocol can support protocol-specific options to configure that
|
||||
protocol. For example, the `git` protocol supports specifying a `ref`
|
||||
query parameter that tells it what ref to checkout for that Git
|
||||
repository.
|
||||
|
||||
The options are specified as query parameters on the URL (or URL-like string)
|
||||
given to go-getter. Using the Git example above, the URL below is a valid
|
||||
input to go-getter:
|
||||
|
||||
github.com/hashicorp/go-getter?ref=abcd1234
|
||||
|
||||
The protocol-specific options are documented below the URL format
|
||||
section. But because they are part of the URL, we point it out here so
|
||||
you know they exist.
|
||||
|
||||
### Subdirectories
|
||||
|
||||
If you want to download only a specific subdirectory from a downloaded
|
||||
directory, you can specify a subdirectory after a double-slash `//`.
|
||||
go-getter will first download the URL specified _before_ the double-slash
|
||||
(as if you didn't specify a double-slash), but will then copy the
|
||||
path after the double slash into the target directory.
|
||||
|
||||
For example, if you're downloading this GitHub repository, but you only
|
||||
want to download the `testdata` directory, you can do the following:
|
||||
|
||||
```
|
||||
https://github.com/hashicorp/go-getter.git//testdata
|
||||
```
|
||||
|
||||
If you downloaded this to the `/tmp` directory, then the file
|
||||
`/tmp/archive.gz` would exist. Notice that this file is in the `testdata`
|
||||
directory in this repository, but because we specified a subdirectory,
|
||||
go-getter automatically copied only that directory contents.
|
||||
|
||||
Subdirectory paths may contain may also use filesystem glob patterns.
|
||||
The path must match _exactly one_ entry or go-getter will return an error.
|
||||
This is useful if you're not sure the exact directory name but it follows
|
||||
a predictable naming structure.
|
||||
|
||||
For example, the following URL would also work:
|
||||
|
||||
```
|
||||
https://github.com/hashicorp/go-getter.git//test-*
|
||||
```
|
||||
|
||||
### Checksumming
|
||||
|
||||
For file downloads of any protocol, go-getter can automatically verify
|
||||
a checksum for you. Note that checksumming only works for downloading files,
|
||||
not directories, but checksumming will work for any protocol.
|
||||
|
||||
To checksum a file, append a `checksum` query parameter to the URL. go-getter
|
||||
will parse out this query parameter automatically and use it to verify the
|
||||
checksum. The parameter value can be in the format of `type:value` or just
|
||||
`value`, where type is "md5", "sha1", "sha256", "sha512" or "file" . The
|
||||
"value" should be the actual checksum value or download URL for "file". When
|
||||
`type` part is omitted, type will be guessed based on the length of the
|
||||
checksum string. Examples:
|
||||
|
||||
```
|
||||
./foo.txt?checksum=md5:b7d96c89d09d9e204f5fedc4d5d55b21
|
||||
```
|
||||
|
||||
```
|
||||
./foo.txt?checksum=b7d96c89d09d9e204f5fedc4d5d55b21
|
||||
```
|
||||
|
||||
```
|
||||
./foo.txt?checksum=file:./foo.txt.sha256sum
|
||||
```
|
||||
|
||||
When checksumming from a file - ex: with `checksum=file:url` - go-getter will
|
||||
get the file linked in the URL after `file:` using the same configuration. For
|
||||
example, in `file:http://releases.ubuntu.com/cosmic/MD5SUMS` go-getter will
|
||||
download a checksum file under the aforementioned url using the http protocol.
|
||||
All protocols supported by go-getter can be used. The checksum file will be
|
||||
downloaded in a temporary file then parsed. The destination of the temporary
|
||||
file can be changed by setting system specific environment variables: `TMPDIR`
|
||||
for unix; `TMP`, `TEMP` or `USERPROFILE` on windows. Read godoc of
|
||||
[os.TempDir](https://golang.org/pkg/os/#TempDir) for more information on the
|
||||
temporary directory selection. Content of files are expected to be BSD or GNU
|
||||
style. Once go-getter is done with the checksum file; it is deleted.
|
||||
|
||||
The checksum query parameter is never sent to the backend protocol
|
||||
implementation. It is used at a higher level by go-getter itself.
|
||||
|
||||
If the destination file exists and the checksums match: download
|
||||
will be skipped.
|
||||
|
||||
### Unarchiving
|
||||
|
||||
go-getter will automatically unarchive files into a file or directory
|
||||
based on the extension of the file being requested (over any protocol).
|
||||
This works for both file and directory downloads.
|
||||
|
||||
go-getter looks for an `archive` query parameter to specify the format of
|
||||
the archive. If this isn't specified, go-getter will use the extension of
|
||||
the path to see if it appears archived. Unarchiving can be explicitly
|
||||
disabled by setting the `archive` query parameter to `false`.
|
||||
|
||||
The following archive formats are supported:
|
||||
|
||||
* `tar.gz` and `tgz`
|
||||
* `tar.bz2` and `tbz2`
|
||||
* `tar.xz` and `txz`
|
||||
* `zip`
|
||||
* `gz`
|
||||
* `bz2`
|
||||
* `xz`
|
||||
|
||||
For example, an example URL is shown below:
|
||||
|
||||
```
|
||||
./foo.zip
|
||||
```
|
||||
|
||||
This will automatically be inferred to be a ZIP file and will be extracted.
|
||||
You can also be explicit about the archive type:
|
||||
|
||||
```
|
||||
./some/other/path?archive=zip
|
||||
```
|
||||
|
||||
And finally, you can disable archiving completely:
|
||||
|
||||
```
|
||||
./some/path?archive=false
|
||||
```
|
||||
|
||||
You can combine unarchiving with the other features of go-getter such
|
||||
as checksumming. The special `archive` query parameter will be removed
|
||||
from the URL before going to the final protocol downloader.
|
||||
|
||||
## Protocol-Specific Options
|
||||
|
||||
This section documents the protocol-specific options that can be specified for
|
||||
go-getter. These options should be appended to the input as normal query
|
||||
parameters ([HTTP headers](#headers) are an exception to this, however).
|
||||
Depending on the usage of go-getter, applications may provide alternate ways of
|
||||
inputting options. For example, [Nomad](https://www.nomadproject.io) provides a
|
||||
nice options block for specifying options rather than in the URL.
|
||||
|
||||
## General (All Protocols)
|
||||
|
||||
The options below are available to all protocols:
|
||||
|
||||
* `archive` - The archive format to use to unarchive this file, or "" (empty
|
||||
string) to disable unarchiving. For more details, see the complete section
|
||||
on archive support above.
|
||||
|
||||
* `checksum` - Checksum to verify the downloaded file or archive. See
|
||||
the entire section on checksumming above for format and more details.
|
||||
|
||||
* `filename` - When in file download mode, allows specifying the name of the
|
||||
downloaded file on disk. Has no effect in directory mode.
|
||||
|
||||
### Local Files (`file`)
|
||||
|
||||
None
|
||||
|
||||
### Git (`git`)
|
||||
|
||||
* `ref` - The Git ref to checkout. This is a ref, so it can point to
|
||||
a commit SHA, a branch name, etc. If it is a named ref such as a branch
|
||||
name, go-getter will update it to the latest on each get.
|
||||
|
||||
* `sshkey` - An SSH private key to use during clones. The provided key must
|
||||
be a base64-encoded string. For example, to generate a suitable `sshkey`
|
||||
from a private key file on disk, you would run `base64 -w0 <file>`.
|
||||
|
||||
**Note**: Git 2.3+ is required to use this feature.
|
||||
|
||||
* `depth` - The Git clone depth. The provided number specifies the last `n`
|
||||
revisions to clone from the repository.
|
||||
|
||||
|
||||
The `git` getter accepts both URL-style SSH addresses like
|
||||
`git::ssh://git@example.com/foo/bar`, and "scp-style" addresses like
|
||||
`git::git@example.com/foo/bar`. In the latter case, omitting the `git::`
|
||||
force prefix is allowed if the username prefix is exactly `git@`.
|
||||
|
||||
The "scp-style" addresses _cannot_ be used in conjunction with the `ssh://`
|
||||
scheme prefix, because in that case the colon is used to mark an optional
|
||||
port number to connect on, rather than to delimit the path from the host.
|
||||
|
||||
### Mercurial (`hg`)
|
||||
|
||||
* `rev` - The Mercurial revision to checkout.
|
||||
|
||||
### HTTP (`http`)
|
||||
|
||||
#### Basic Authentication
|
||||
|
||||
To use HTTP basic authentication with go-getter, simply prepend `username:password@` to the
|
||||
hostname in the URL such as `https://Aladdin:OpenSesame@www.example.com/index.html`. All special
|
||||
characters, including the username and password, must be URL encoded.
|
||||
|
||||
#### Headers
|
||||
|
||||
Optional request headers can be added by supplying them in a custom
|
||||
[`HttpGetter`](https://godoc.org/github.com/hashicorp/go-getter#HttpGetter)
|
||||
(_not_ as query parameters like most other options). These headers will be sent
|
||||
out on every request the getter in question makes.
|
||||
|
||||
### S3 (`s3`)
|
||||
|
||||
S3 takes various access configurations in the URL. Note that it will also
|
||||
read these from standard AWS environment variables if they're set. S3 compliant servers like Minio
|
||||
are also supported. If the query parameters are present, these take priority.
|
||||
|
||||
* `aws_access_key_id` - AWS access key.
|
||||
* `aws_access_key_secret` - AWS access key secret.
|
||||
* `aws_access_token` - AWS access token if this is being used.
|
||||
|
||||
#### Using IAM Instance Profiles with S3
|
||||
|
||||
If you use go-getter and want to use an EC2 IAM Instance Profile to avoid
|
||||
using credentials, then just omit these and the profile, if available will
|
||||
be used automatically.
|
||||
|
||||
### Using S3 with Minio
|
||||
If you use go-gitter for Minio support, you must consider the following:
|
||||
|
||||
* `aws_access_key_id` (required) - Minio access key.
|
||||
* `aws_access_key_secret` (required) - Minio access key secret.
|
||||
* `region` (optional - defaults to us-east-1) - Region identifier to use.
|
||||
* `version` (optional - defaults to Minio default) - Configuration file format.
|
||||
|
||||
#### S3 Bucket Examples
|
||||
|
||||
S3 has several addressing schemes used to reference your bucket. These are
|
||||
listed here: http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingBucket.html#access-bucket-intro
|
||||
|
||||
Some examples for these addressing schemes:
|
||||
- s3::https://s3.amazonaws.com/bucket/foo
|
||||
- s3::https://s3-eu-west-1.amazonaws.com/bucket/foo
|
||||
- bucket.s3.amazonaws.com/foo
|
||||
- bucket.s3-eu-west-1.amazonaws.com/foo/bar
|
||||
- "s3::http://127.0.0.1:9000/test-bucket/hello.txt?aws_access_key_id=KEYID&aws_access_key_secret=SECRETKEY®ion=us-east-2"
|
||||
|
||||
### GCS (`gcs`)
|
||||
|
||||
#### GCS Authentication
|
||||
|
||||
In order to access to GCS, authentication credentials should be provided. More information can be found [here](https://cloud.google.com/docs/authentication/getting-started)
|
||||
|
||||
#### GCS Bucket Examples
|
||||
|
||||
- gcs::https://www.googleapis.com/storage/v1/bucket
|
||||
- gcs::https://www.googleapis.com/storage/v1/bucket/foo.zip
|
||||
- www.googleapis.com/storage/v1/bucket/foo
|
||||
|
||||
#### GCS Testing
|
||||
|
||||
The tests for `get_gcs.go` require you to have GCP credentials set in your environment. These credentials can have any level of permissions to any project, they just need to exist. This means setting `GOOGLE_APPLICATION_CREDENTIALS="~/path/to/credentials.json"` or `GOOGLE_CREDENTIALS="{stringified-credentials-json}"`. Due to this configuration, `get_gcs_test.go` will fail for external contributors in CircleCI.
