By default, when listing images the ComputeServiceAdapter adds the
default credentials for each image. This is not done when images are
created by the image extension, and NPEs can appear in code that assumes
the default credentials are there, as the field is not nullable.
This change tries to populate the known node credentials for images
created form nodes, and falls back to the default strategy to add the
default credentials to an image if there are not known credentials.
CentOS’ officially-supported AMIs are hosted on the AWS Marketplace.
This adds support for those images, recognising the AMI naming
convention and ensuring the OS metadata is parsed correctly and the
correct SSH login name is used.
There is no change to the default jclouds configuration and the
official CentOS images will not be detected by default. To use these
images, you must alter the ami-query properties to include searching
the “AWS Marketplace”, which has an owner ID of 679593333241. You must
also manually log on to the AWS Marketplace, select your chosen CentOS
image, and “subscribe” to it (you can do this by proceeding as if to
launch an image, but stopping after you have agreed to the subscription
and before launching).
As all methods use POST we can not use the method to determine if funciton is idempotent.
We therefore set all as idempotent to nullify that check and add a custom
IOException retry handler to determine if commands should be retried on IOException.
The custom hander extends the BackoffLimitedRetryHandler, the current handler, so all other behaviour is not affected.
This does not retry any POST methods unless it's ACTION starts with 'Describe'. These functions are idempotent, and therefore safe to retry.

The intention is to use @SinceApiVersion for this purpose, but that
would affect a number of APIs, and we would want to have good test
coverage before merging that change (in
FormSignerUtils#getAnnotatedApiVersion). However, there is some issue
wth certain tests at resent that means we cannot successfully test
all APIs that make use of @SinceApiVersion in order to assure
ourselves that FormSignerUtils will not introduce some problem.
See https://github.com/jclouds/jclouds/pull/1102#issuecomment-302682049
for details.
This annotation is introduced as a temporary measure in order to
decouple the functionality of FormSignerUtils#getAnnotatedApiVersion
from @SinceApiVersion and the tests in question. It can be removed and
replaced by @SinceApiVersion when those tests are fixed.
Designates that a method overrides the {@link ApiVersion} on the class
with a specific value.
This is a follow-up to https://github.com/jclouds/jclouds/pull/1091
and particularly the comment at
https://github.com/jclouds/jclouds/pull/1091#issuecomment-299202429:
I have been trying this out and I think we will need to extend it for
practical purposes; if you want to create a VPC and subnet and then
deploy a machine on to it, you also need to jump through a few other
hoops apart from creating the subnet:
- modify the subnet attributes to permit auto-assign public
IP ("ModifySubnetAttribute")
- create an Internet Gateway on the VPC ("CreateInternetGateway")
- get and then modify the routing table of the subnet to add a public
(0.0.0.0/0) route through the newly added gateway ("CreateRoute" and
friends)
There are three AWS APIs needed for the above, an `InternetGatewayApi`,
a `RouteTableApi` and a method in the subnet API, I guess, for modifying
attributes on subnets. This PR contains the `InternetGatewayApi`.
Readers can confuse this with 1. Found via error-prone. Fixed via:
find -name \*.java | xargs sed -i 's/\( [0-9][0-9]*\)l/\1L/g'
find -name \*.java | xargs sed -i 's/\(([0-9][0-9]*\)l/\1L/g'
* dynamically call TypeToken.isSupertypeOf with Guava 19 and later and
TypeToken.isAssignableFrom with Guava 18 and earlier
* consume or ignore values from methods with CheckReturnValue
* replace usage of removed Iterators.emptyIterator
This commit refactors the ImageCacheSupplier to act as a
proper cache. It is used by the ImageExtesion and all operations
on the images are propagated to the cache.
A method has also been added to the TemplateBuilder to let users
force a cache refresh. There have been several requests to provide a way
to disable image caching in the compute abstraction, and this new method
should fix that.
