Epinio, CLI settings

The Epinio command line client uses a settings file to store information which has to persist across invocations. This document discusses various aspects around this.

Table Of Contents​

Location​

Epinio's settings files is located by default at ~/.config/epinio/settings.yaml.

The location can be changed from command to command by specifying a different path with the global command line option --settings-file.

A more permanent change is possible by setting the environment variable EPINIO_SETTINGS to the desired path.

Contents​

Epinio's settings contains

  • The name of the namespace currently targeted.
  • Epinio API user name
  • Epinio API password (base64 encoded)
  • Epinio API Token
  • Epinio API urls (regular and websocket)
  • Epinio API certificate

The namespace can be changed by running epinio target with the name of the desired namespace as its single argument.

Username and password are used by the client to authenticate itself when talking to Epinio's API server. The epinio login [URL] command asks for your username and password, checks the validity of the credentials, and saves the information to the settings.

The token is an object generated when you log in with an OIDC provider using the epinio login --oidc command.

The token combines the access_token and refresh_token.

If a token is present, it will be used to authenticate and takes precedence over the username and password.

The installation uses the wildcard domain omg.howdoi.website and the epinio-ca issuer by default.

The epinio login [URL] checks if the associated certificate is signed by an unknown CA and it asks you if you want to trust it and save it to the settings so that future invocations of the client are able to verify the actual certificate when talking to Epinio's API server.

The epinio settings update-ca updates the API url and the certificate.

Commands​

The Epinio command line client currently provides 3 commands explicitly targeting the settings. These are:

  1. epinio target

    As noted in the previous section, this command changes the namespace to use with all other commands.

  2. epinio settings show

    This command shows the details of the currently stored settings. An exception is made for the certificate field, due to its expected size. The command's output only notes if certificate data is present or not.

  3. epinio login [URL]

    Epinio allows users to switch between multiple installations (on different clusters) by simply using a different settings file.

    When such is done the credentials, cert data, and URLs stored in the settings will not match the newly targeted cluster, except by coincidence.

    Logging in and pointing to the newly targeted installation will create new settings file storing credentials, cert data, and URLs with information retrieved from the new cluster.
