docker-for-aws-gen

Generates docker-for-aws CloudFormation templates based on configuration.

Manager

Custom tags

• affects .Resources.ManagerAsg.Properties.Tags

Adds custom tags to the AutoScalingGroup of the managers. These tags propagates to the instances.

Example:

const opts = {
  Manager: {
    CustomTags: {
      "com.mytag": "value",
    },
  },
}

Daemon Labels

• affects .Resources.ManagerLaunchConfig<Version>.Properties.UserData

Adds a custom array of labels to the manager docker daemon.

Example:

const opts = {
  Manager: {
    Labels: [
      "com.mylabel=lol",
      "com.mymachine",
    ],
  },
}

Provisioning code

• affects .Resources.ManagerLaunchConfig<Version>.Properties.UserData

Sets a custom code to run after the daemon has started but while the manager machine is still launching.

Example:

const opts = {
  Manager: {
    AfterDaemonStarted: [
      "echo this is cool!\n",
      "echo :D\n",
    ],
  },
}

Workers

Workers makes the cattle of workers more granular. The options for these are just like the options for Manager but you specify an array of them with an extra field: Name.

For instance:

const opts = {
  Workers: [
    {
      Name: "Infra",
      Labels: [
        "com.mylabel=lol",
        "com.mymachine",
      ],
      CustomTags: {
        "com.mytag": "value",
      },
      AfterDaemonStarted: [
        "echo this is cool!\n",
        "echo :D\n",
      ],
    }
  ]

}

Full Example

Having the following config.json:

{
  "Manager": {
    "Labels": [
      "com.type=test"
    ],
    "CustomTags": {
      "test": "test"
    },
    "AfterDaemonStarted": [
      "echo this is cool!\n",
      "echo :D\n"
    ]
  },

  "Workers": [
    {
      "Name": "Infra",
      "Labels": [
        "com.type=test"
      ],
      "CustomTags": {
        "test": "test"
      },
      "AfterDaemonStarted": [
        "echo this is cool!\n",
        "echo :D\n"
      ]
    }
  ]
}

and a docker-for-aws template in ./templates/17.06.0-ce/edge/template.json:

$ docker-for-aws-gen -t ./templates/17.06.0-ce/edge/template.json -c ./config.json


{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Conditions": {
    "CloudStorSelected": {
      "Fn::Equals": [
        {
          "Ref": "EnableCloudStor"
        },
        "yes"
        ...
