Remove upstream repo dependency

The purpose of this spec is to remove the repo-clone play from OSAD.

Problem description

Presently the repo-clone-mirror play is responsible for cloning the upstream repository that Rackspace maintains into the repo containers. While this process is simple enough it does bring with it a reliance on an upstream deployer/vendor. OSAD already has the ability to build its own python packages which is the process used to do all gate check testing so it should also be the default means to deploy an OSAD environment.

Proposed change

  • Remove the repo-clone-mirror.yml play
  • Change repo-install.yml to use repo-build.yml as it’s included method.
  • Modify the pip install role to remove the install requirement using the upstream mirror.

Alternatives

Leave everything the way it is.

Playbook impact

Changes the repo create process to always build. This will only impact deployers that are using the repo-servers and will ensure that the system is always building the correct packages.

When bootstrapping a new environment the pip install role is used throughout the stack. This would modify that role to always pull upstream pip unless otherwise instructed, through the use of user_vars, to go elsewhere.

Performance impact

Repo clone was intended to be a faster means of delivering packages to the deployment infrastructure however in testing repo clone and repo build operate at roughly the same speed.

Deployer impact

This change will be unnoticeable to the deployer.

Work items

  • Delete the repo-clone-mirror.yml play
  • Change the include in repo-install.yml ‘s/repo-clone-mirror.yml/repo-build.yml/’

Testing

This is already being tested on every build within upstream OSAD.
