This change checks for closed iochans related to the log polling
function and will break out of the loop when both channels are closed.
Which is an indicator that the SSM session has been terminated by some
external process. This fixes an issue where Packer hangs, due to the
infinite loop, when an SSM session is killed outside of Packer.
Related to #9442
withouth this fix we would have had to do
```hcl
temporary_iam_instance_profile_policy_document {
statement {
action = ["*"]
effect = "Allow"
resource = ["*"]
}
version = "2012-10-17"
}
```
instead of the same document but with capitalised fields
PutRolePolicy & AddRoleToInstanceProfile are eventually consistent but it is not possible to wait for them to be done here: 0785c2f6fc/builder/amazon/common/step_iam_instance_profile.go (L117-L134) which was causing the `CreateFleet` to fail (100% for me). So for now we retry a bit later. Waiting 5 seconds after the previously linked code also fixed this.

* Add a test to ensure the proper host is returned when using session_manager
* Add a basic driver test for the validating that the SSMDriver will fail if the plugin is not in the path.
Connectivity for WinRM works for the initial connection, but fails to upload any provisioning scripts - need to dive in deeper.
For now connectivity over SSH works as expected.
* Update security group creation step skip ingress rules if using session manager
* Update create ssm tunnel step to dynamically set a session port
* Add SSHPort function to common to return session-manager tunnel port
* Update SSHHost to return proper host for session-manager
* Add a bunch of hard coded values for testing on port 8081; ssh configs
are set to localhost and 8081
* Add a base drive for communicating with the session manager plugin
* Update step for creating tunnel to actually create SSM session tunnel via driver
* mapstructure-to-hcl2: when we see a map generate an attribute spec and not a block spec
this will alow to do
tags = {
key = "value"
}
instead of
tags {
key = "value"
}
This will also enable using variables directly for those tags
* generate code
* update tests
* Add golangci-lint as linting tool
* Disable failing staticchecks to start; GitHub issue to handle coming soon
* Run `goimports -w` to repair all source files that have improperly
formatted imports
* makefile: Add ci-lint target to run on travis
This change adds a new make target for running golangci-lint on newly
added Go files only. This target is expected to run during Packer ci builds.
* .github/contributing: Add code linting instructions
* travis: Update job configuration to run parallel builds
This follows #8232 which added the code to generate the code required to parse
HCL files for each packer component.
All old config files of packer will keep on working the same. Packer takes one
argument. When a directory is passed, all files in the folder with a name
ending with “.pkr.hcl” or “.pkr.json” will be parsed using the HCL2 format.
When a file ending with “.pkr.hcl” or “.pkr.json” is passed it will be parsed
using the HCL2 format. For every other case; the old packer style will be used.
## 1. the hcl2template pkg can create a packer.Build from a set of HCL (v2) files
I had to make the packer.coreBuild (which is our one and only packer.Build ) a public struct with public fields
## 2. Components interfaces get a new ConfigSpec Method to read a file from an HCL file.
This is a breaking change for packer plugins.
a packer component can be a: builder/provisioner/post-processor
each component interface now gets a `ConfigSpec() hcldec.ObjectSpec`
which allows packer to tell what is the layout of the hcl2 config meant
to configure that specific component.
This ObjectSpec is sent through the wire (RPC) and a cty.Value is now
sent through the already existing configuration entrypoints:
Provisioner.Prepare(raws ...interface{}) error
Builder.Prepare(raws ...interface{}) ([]string, error)
PostProcessor.Configure(raws ...interface{}) error
