-Ansible role for clever cloud deployment
+Ansible role for Clever Cloud deployment
=======
-Clever deploy
-=========
This role deploys applications on clever cloud (https://www.clever-cloud.com).
-It handles the publication over git, as well as domain names, environment variables and log drains configuration.
+It handles the publication over git, as well as configuring domain names, environment variables and log drains, dedicated build instances, and scalability parameters.
Requirements
------------
-This role requires `clever-tools` version `2.6.1` or higher.
+This role requires [`clever-tools`](https://github.com/CleverCloud/clever-tools) CLI version `2.6.1` or higher.
+
+If you want to configure this role with [Dhall](https://dhall-lang.org/) instead of YAML, the dhall bindings defined in the `dhall/` directory will need Dhall version `1.26.0` or higher.
Role Variables
--------------
-Variables for the application
-- `clever_token`: clever_cloud token, mandatory.
-- `clever_secret`: clever_cloud secret, mandatory.
-- `clever_app`: the id of the app to link, mandatory.
-- `clever_env`: a dict of environment variables for the application (without add_ons one already available), optional.
-- `clever_base_env`: a dict set in vars/main.yml with safe default and mandatory variables for an app to be run on clever. ` clever_base_env | combine(clever_env)` is passed to `clever env` command
+Variables for the application:
+
+- `clever_token`: clever_cloud token, **mandatory**.
+- `clever_secret`: clever_cloud secret, **mandatory**.
+- `clever_app`: the id of the app to link, **mandatory**.
+- `clever_env`: a dict of environment variables to add to the application, optional.
- `clever_addons`: a list of dict describing addons enabled for the application from which we would use information during deploy, optional.<br/>
Example: `{ name: pg, env_prefix: POSTGRESQL_ADDON }`
-- `clever_app_tasks_file`: tasks file to be executed after environment and addons variables where gathered. Specific to an app, should be use to run migrations. Optional.
-- `clever_haskell_entry_point`: the haskell executable name to be executed by clever cloud, optional.
+- `clever_app_tasks_file`: path to an Ansible tasks file to be executed after environment and addons variables where gathered. Specific to an application and should be use to run migrations for example. Optional.
- `clever_domain`: the domain from which the application should be reachable, optional.
-- _Obsolete_: `domain`: Same as above but was replaced by `clever_domain` since v1.4 of this role.
- `clever_syslog_server`: UDP Syslog server to be used as UDPSyslog drain for the application, optional. Example: `udp://198.51.100.51:12345`.
-- _Obsolete_: `syslog_server`: Same as above but was replaced by `clever_syslog_server` since v1.5 of this role.
-- _Obsolete_: `clever_metrics`: metrics used to be disabled by default. Now they are enabled by default and can be explicitly disabled with `clever_disable_metrics`.
+- _Obsolete_: `clever_metrics`: metrics used to be disabled by default. Now they are enabled by default on Clever-Cloud and can be explicitly disabled with the `clever_disable_metrics` variable.
- `clever_disable_metrics`: a boolean to disable metrics support. Optional, default to `false`.
-- `clever_env_output_file`: as a post deploy task you might need to retrieve the full Clever environment configuration (i.e. with addon env variables). If this variable is set to a filename then the env will be retrieved after a successful deploy inside this file. Optional.
+- `clever_env_output_file`: as a post deploy task you might need to retrieve the full Clever environment configuration (i.e. with addon env variables). If this variable is set to a filename then the env will be retrieved after a successful deploy and written to this file. Beware, the resulting file will contain sensitive information (addon passwords, …). Optional.
- `clever_build_flavor`: an optional text value used to configure the size of the dedicated build instance (for instance `S` or `XL`). If not defined, it delegates to clever cloud default behaviour. Setting `disabled` disables the dedicated build instance altogether.
- `clever_scaling`: an optional object used to configure the runtime instances flavours and numbers. If not defined, it delegates to clever cloud default behaviour.
Variables specific to deployment, default should be fine:
+
- `clever_cli_version`: Version of clever cli tools, default to `2.6.1`.
- `clever_user_path`: Path relative to ansible_user home dir where cli tools and helpers are installed default to `.local/bin`.
-- `clever_app_root`: Path of the application to deploy, default to `app_root` if defined or `"{{ playbook_dir }}/.."`, ie ansible directory in the root of the application.
+- `clever_app_root`: Path of the application to deploy, default to `app_root` if defined or `"{{ playbook_dir }}/.."` otherwise. I.e. the default behavior will work fine if you define a playbook using this role in a one level deep directory (e.g. `deployment/`) of the root of the application.
- `clever_app_confdir`: Path where to store clever cloud data specific to this application, default to `"{{ clever_app_root }}/.clever_cloud"`
- `clever_login_file`: Path to store login information. Default to `"{{ clever_app_confdir }}/login"`.
+Variables specific to Haskell applications:
+
+- `clever_haskell_entry_point`: the haskell executable name to be executed by clever cloud, optional.
+
Scaling configuration

Dependencies
------------
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
- - hosts: servers
+ - hosts: localhost
roles:
- - { role: fretlink.clever, clever_app: 42, clever_token: "{{ vault_clever_token }}", clever_secret: "{{ vault_clever_secret}}" }
+ - role: fretlink.clever,
+ vars:
+ clever_app: app_00000000-0000-0000-0000-000000000000,
+ clever_token: "{{ vault_clever_token }}",
+ clever_secret: "{{ vault_clever_secret}}"
