Doact is a Terraform module to automate the deployment and hosting process of your own runners on Digital Ocean cloud to run jobs in your GitHub Actions workflows. It makes it easy to automate all your software workflows, now with world-class CI/CD. Build, test, and deploy your code right from GitHub.
Doact sets up a self-hosted runner on the cloud. Self-hosted runners offer more control of hardware, operating system, and software tools than GitHub-hosted runners provide. With self-hosted runners, you can choose to create a custom hardware configuration with more processing power or memory to run larger jobs, install software available on your local network, and choose an operating system not offered by GitHub-hosted runners. You can read more about self-hosted runner here.
Note: Currently doact supports machines with Linux X64 architecture.
Terraform
Ensure you have Terraform installed. A handy tool to manage your Terraform version is tfenv.
On macOS it is simple to install tfenv using brew.
$ brew install tfenvNext install a Terraform version.
$ tfenv install <version>Note: doact is written to work with Terraform 0.11.x - it will not run on 0.12.x
DigitalOcean Personal Access Token
This module uses DigitalOcean (DO) provider is used to interact with the resources supported by DigitalOcean. The provider needs to be configured with the proper credentials before it can be used. Check Terraform DigitalOcean Provider for more detailed usage and examples. To generate a personal access token, follow this tutorial.
Note: Access tokens require repo scope for private repos and public_repo scope for public repos.
Github personal access token
The module requires Github personal access token for the admin access to the repository and to configure the runner. You can create a personal access token by following this tutorial.
SSH Public Key
Your SSH Pulic key is required to give you full access to the Droplet on which your runner is hosted. Droplets are virtual machines that run on top of virtualized hardware. You can generate your own SSH Public Key by following this tutorial.
Update the values inside terraform.tfvars file for better experience.
Run the following commands to use the module:
To initialize Terraform:
$ terraform initTo inspect the resources that will be created:
$ terraform planTo deploy the runner :
$ terraform applyTo delete the runner :
$ terraform destroyNote: The above command will use the default values defined inside variables.tf file. You can change the values if required.
Optional
The ssh-keys module has been added with Docat v2.x.x to make it easier to deploy your SSH Key on Digital Ocean. Just Paste your SSH Public Key inside the file user_id_rsa.pub and peroform the above actions.
