This change updates handling of pool aliases to allow for more than a
single pool to be configured as an alias pool. Without this change if
multiple pools are configured as an alias the last one to configure it
is set as the alias for that pool.
Additionally, redis testing requirements are removed in favor of
mock_redis. Without this change a redis server is required to run
vmpooler tests.
This commit updates vmpooler to allow the API component and dashboard to
run separately from pool_manager. Without this change vmpooler does not
offer a mechanism to run only the API, or pool_manager components.
Two instances of hardcoded puma environment settings are removed. This
is still set in the init script explicitly as well as via an environment
variable in the dockerfile.
To extend the mechanism of running the API or pool_manager components to
instances running in docker an entrypoint is added in the dockerfile.
The entrypoint allows a user to specify whether to run the API or
pool_manager components when running the application. The default
behavior is preserved where both components are run.
To support these changes vmpooler.rb is updated to allow more of the
configuration to be specified via individual environment variables. It
was already possible to specify the entire config block as an
environment variable, but this is more difficult to manage and less of a
standard implementation than specifying individual parameters. Where
specified environment variable options will override a value configured
via the configuration file or environment.
The running pool configuration when starting pool_manager is loaded to
redis at pool_manager start time. This allows the API to load the
running pool configuration from redis and be able to run without
requiring the pool configuration.
Lastly, the dockerfile leveraging entrypoint will no longer start
vmpooler with the init script or write logs to a file. Instead, LOGFILE
is set to /dev/stdout and the vmpooler application is started directly.
This behavior is preferred because the log file writes to disk are an
unnecessary overhead. Without this change the docker installation will
attempt to daemonize the vmpooler application and always requires puma.
Previously all of the spec tests for VM Pooler were all together in the specs
directory. However some tests require a working local Redis server to operate
and other instead mock all external dependencies. This commit splits the test
files between unit and integration, where integration tests require a working
Redis instance, and unit tests do not. This commit also removes the root
`vmpooler` directory as it is not required. The tests rake test still operates
correctly.
This commit also adds the mock_redis library for testing for the pool_manager.
