edeliver_fork v1.4.5 Edeliver

Execute edeliver tasks on the production / staging nodes.

This internal module provides functions on the nodes which are used by some edeliver tasks e.g. to get the running release version (edeliver version), show the pending migrations (edeliver show migrations) or install pending migrations (edeliver migrate).

In addition it represents the edeliver application callback module and starts a process registered locally as Edeliver whichs onliest purpose is to be able to detect whether the release was successfully started. This requires to start edeliver as last application in the release.

Summary

Functions

Returns the current directory containing the ecto migrations

Waits until the edeliver application is started

Runs the edeliver command on the erlang node

Starts the edeliver application

Starts this gen-server registered locally as Edeliver

Functions

list_pending_migrations(application_name, application_version, ecto_repository \\ [])

Prints the pending ecto migrations

migrate(application_name, application_version, ecto_repository, direction, migration_version \\ :all)

Runs the pending ecto migrations

migrations_dir(application_name, application_version)

Returns the current directory containing the ecto migrations.

monitor_startup_progress(application_name)

Specs

monitor_startup_progress(application_name :: atom) :: :ok

Waits until the edeliver application is started.

If the edeliver application is added as last application in the :applications section of the application/0 fun in the mix.exs this waits until all applications are started. This can be used as rpc call after running the asynchronous bin/$APP start command to wait until all applications started and then return ok.

release_version(application_name, application_version \\ nil)

Specs

release_version(application_name :: atom, application_version :: String.t) :: String.t

Returns the running release version

which is either the :current version or the :permanent version.

run_command(list)

Specs

run_command(args :: [term]) :: no_return

Runs the edeliver command on the erlang node

started as:

  bin/$APP rpc Elixir.Edeliver run_command '[[command_name, "$APP", arguments...]].'

The first argument must be the name of the command, the second argument the name of the main application and all further arguments are passed to the function thats name is equal to the command name.

start(type, args)

Specs

start(term, term) :: {:ok, pid}

Starts the edeliver application

including the Edeliver.Supervisor process supervising the Edeliver generic server.

start_link()

Specs

start_link :: {:ok, pid}

Starts this gen-server registered locally as Edeliver
