marathon-env

Manage the environment variables of your Marathon applications easily with a tool cli

Quickstart

Create an yml file: my-website.yml and add these content:

groups:
  - name: my_website_backend
    envs:
      NODE_ENV: production
      DB_HOST: db.internal.myapp
      DB_PORT: 3306
  - name: my_website_frontend
    envs:
      GOOGLE_ANALYTICS_ID: "UA-12345"
      JQUERY_VERSION: "2.2.5"
  - name: my_website_general
    envs:
      YOU_CAN_PUT_ANY: "NAME"

Add ENV_GROUP label with all groups (comma-separated) that you want to apply environment variables in your Marathon application.

Example:

{
  "id": "http",
  "cmd": "python -m SimpleHTTPServer $PORT",
  "mem": 50,
  "cpus": 0.1,
  "instances": 1,
  "labels": {
    "ENV_GROUP": "my_website_backend,my_website_general"
  }
}

Done! Now, everytime you want to redefine environment variables, just change your yml file and apply with:

marathon-env --url <YOUR-MARATHON-URL> --username <YOU-MARATHON-HTTP-USER> --password <YOU-MARATHON-HTTP-PASSWORD>
