Simple release deliverer for Elixir.

Dicon gets most of the information needed to deploy and manage releases from the configuration of the :dicon application. For example, in your application's configuration (my_app/config/config.exs):

config :dicon,
  target_dir: "/home/deploy/my_app"

Configuration options

• :otp_app - an atom that specifies the name of the application being deployed.

• :target_dir - a binary that specifies the directory where the release tarball will be extracted into.

• :hosts - a list of host_name atoms that specifies which servers the release should be deployed to. Each host should be then configured under the :dicon application. See the "Configuration for hosts" section below. authoritys should be "authorities" according to this RFC, i.e., binaries with an optional userinfo followed by @, an hostname, and an optional port preceded by :. For example, me:mypassword@example.com:22.

• :executor - a module that will be used to execute commands on servers. By default, it's Dicon.SecureShell.

Configuration for hosts

Each host listed in the :hosts configuration option mentioned above can be configured under the :dicon application. For example, take this configuration:

config :dicon,
  hosts: [:app01, :app02]

Now the :app01 and :app02 hosts can be configured like this:

config :dicon, :app01,
  authority: "myuser@app01.example.net"

These are the supported host configuration options:

• :authority - (binary) an "authority" according to this RFC, that is, a binary with an optional userinfo followed by @, an hostname, and an optional port preceded by :. For example, "me:mypassword@example.net:22".

• :os_env - (map) a map of environment variable name (as a binary) to value (as a binary). These environment variables will be used when running commands on the target host.

• :apps_env - (keyword list) a keyword list of application to configuration that can be used to override the configuration for some applications on the target host.

Configuration for executors

Each executor can be configured differently; to configure an executor, specify the configuration for that executor under the configuration for the :dicon application.

config :dicon, Dicon.SecureShell,
  dir: "..."
