cf-plex

Runs cf commands against multiple Cloud Foundry instances.

Cloud Foundry instances can be specified in three ways:

1. Ad-hoc: add APIs to one default list, and run commands against all of them
2. Groups: add APIs to named groups, and run commands against all APIs in a specified group
3. Batch: specify APIs in environment variables, and run commands only against those in the env vars

Usage

  cf-plex [-g <group>] <cf cli command> [--force]
  cf-plex add-api [-g <group>] <apiUrl> [<username> <password>]
  cf-plex list-apis
  cf-plex remove-api [-g <group>] <apiUrl>

Installation

Go developers

go get github.com/EngineerBetter/cf-plex

Everyone else

Download the latest release for your OS, save it to PATH, rename it cf-plex and make sure it is executable (chmod +x cf-plex).

Detailed Usage

Ad Hoc Mode

Add and remove APIs in one global list.

• cf-plex add-api https://api.some.com username password Add an API to be used
• cf-plex add-api https://api.some.com Add an API to be used, and prompt for credentials
• cf-plex list-apis Show APIs that are active
• cf-plex remove-api https://api.some.com Remove an API

cf-plex manages a set of CF_HOME directories, one for each Cloud Foundry instance you ask it to manage. These are stored in CF_PLEX_HOME.

Group Mode

Manage APIs in named groups. Use cases include operating on all non-production instances at once.

• cf-plex add-api -g nonprod https://api.nonprod.example.com username password Add an API to the 'nonprod' group
• cf-plex list-apis Show all groups and APIs
• cf-plex -g nonprod delete-user admin Delete the admin user only on non-prod
• cf-plex remove-api -g nonprod https://api.nonprod.example.com Remove an API from a group

You may not add a group called "default" or "batch", as these are used internally.

Once any group has been added, APIs not assigned to a group can only be referenced by using -g default. This is to prevent slips whereby a user may forget to specify a group and accidentally run commands against whatever they defined previously.

Groups are implicitly managed: once there are no APIs in a group, it will cease to exist.

CF_HOME directories for APIs in a group are stored in $CF_PLEX_HOME/groups/, which is deleted automatically when the last group is removed.

Batch Mode

Specify API details in CF_PLEX_APIS to avoid manual credential management:

export CF_PLEX_APIS="username^password>https://api.some.com;username^password>https://api.another.com"
cf-plex create-org new-org

State for batch operations is stored separately to interactive mode: that is, each API's CF_HOME is stored as a subdirectory $HOME/$CF_PLEX_HOME/batch.

If your credentials contain the separators used in the example above, you can specify your own as environment variables:

• CF_PLEX_SEP_TRIPLE for the separator between the three items that identify a Cloud Foundry
• CF_PLEX_SEP_CREDS_API for the separator between the user/pass and the API URL
• CF_PLEX_SEP_USER_PASS for the separator betwen the username and the password

cf-plex stores the CF_HOME directories for APIs used in batch mode in $CF_PLEX_HOME/groups/batch. These are left on disk, to prevent unecessary authentication on successive invocations.

Ignoring Errors

cf-plex will fail fast if the cf CLI returns a non-zero exit code against any API. To override this behaviour (ignore the error and continue running the command) specify --force:

# Will continue even if it fails against one API
cf-plex delete org might-not-exist --force

Plugins

CF CLI plugins are managed with an orthogonal home directory of CF_PLUGIN_HOME. cf-plex doesn't do anything with this, so all your usual plugins will be available. If you have a use case that requires plugin isolation, please raise an issue.

Testing

Currently depends on having an account on Pivotal Web Services and BlueMix.

Acknowledgements

In order to prove that plugin behaviour is unaffected by cf-plex, Simon Leung's cli-plugin-echo is vendored as a test fixture.
