This Terraform modules creates a GitLab CI runner. A blog post describes the original version of the the runner. See the post at 040code. The original setup of the module is based on the blog post: Auto scale GitLab CI runners and save 90% on EC2 costs.
BREAKING CHANGE: The module is upgraded to Terraform AWS provider 4.x. All new development will only support the new AWS Terraform provider. We keep a branch
terraform-aws-provider-3to witch we welcome backports to AWS Terraform 3.x provider. Besides reviewing PR's we will do not any active checking on maintance on this branch. We strongly advise to update your deployment to the new provider version. For more details about upgrading see the upgrade guide.
BREAKING CHANGE: By default AWS metadata service ((IMDSv2)[https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html]) is enabled and required for both the agent instance and the docker machine instance. For docker machine this require the GitLab managed docker machines distribution is used. Which the module usages by default.
The runners created by the module use spot instances by default for running the builds using the docker+machine executor.
- Shared cache in S3 with life cycle management to clear objects after x days.
- Logs streamed to CloudWatch.
- Runner agents registered automatically.
The name of the runner agent and runner is set with the overrides variable. Adding an agent runner name tag does not work.
...
overrides = {
name_sg = ""
name_runner_agent_instance = "Gitlab Runner Agent"
name_docker_machine_runners = "Gitlab Runner Terraform"
name_iam_objects = "gitlab-runner"
}
//this doesn't work
agent_tags = merge(local.my_tags, map("Name", "Gitlab Runner Agent"))The runner supports 3 main scenarios:
In this scenario the runner agent is running on a single EC2 node and runners are created by docker machine using spot instances. Runners will scale automatically based on the configuration. The module creates a S3 cache by default, which is shared across runners (spot instances).
In this scenario the multiple runner agents can be created with different configuration by instantiating the module multiple times. Runners will scale automatically based on the configuration. The S3 cache can be shared across runners by managing the cache outside of the module.
In this scenario not docker machine is used but docker to schedule the builds. Builds will run on the same EC2 instance as the agent. No auto scaling is supported.
Ensure you have Terraform installed. The modules is based on Terraform 0.11, see .terraform-version for the used version. A handy tool to mange 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>Ensure you have setup your AWS credentials. The module requires access to IAM, EC2, CloudWatch, S3 and SSM.
In order to be able to destroy the module, you will need to run from a host with both jq and aws installed and accessible in the environment.
On macOS it is simple to install them using brew.
brew install jq awscliThe GitLab runner EC2 instance requires the following service linked roles:
- AWSServiceRoleForAutoScaling
- AWSServiceRoleForEC2Spot
By default the EC2 instance is allowed to create the required roles, but this can be disabled by setting the option allow_iam_service_linked_role_creation to false. If disabled you must ensure the roles exist. You can create them manually or via Terraform.
resource "aws_iam_service_linked_role" "spot" {
aws_service_name = "spot.amazonaws.com"
}
resource "aws_iam_service_linked_role" "autoscaling" {
aws_service_name = "autoscaling.amazonaws.com"
}By default the runner is registered on initial deployment. In previous versions of this module this was a manual process. The manual process is still supported but will be removed in future releases. The runner token will be stored in the AWS SSM parameter store. See example for more details.
To register the runner automatically set the variable gitlab_runner_registration_config["registration_token"]. This token value can be found in your GitLab project, group, or global settings. For a generic runner you can find the token in the admin section. By default the runner will be locked to the target project, not run untagged. Below is an example of the configuration map.
gitlab_runner_registration_config = {
registration_token = "<registration token>"
tag_list = "<your tags, comma separated>"
description = "<some description>"
locked_to_project = "true"
run_untagged = "false"
maximum_timeout = "3600"
access_level = "<not_protected OR ref_protected, ref_protected runner will only run on pipelines triggered on protected branches. Defaults to not_protected>"
}For migration to the new setup simply add the runner token to the parameter store. Once the runner is started it will lookup the required values via the parameter store. If the value is null a new runner will be registered and a new token created/stored.
# set the following variables, look up the variables in your Terraform config.
# see your Terraform variables to fill in the vars below.
aws-region=<${var.aws_region}>
token=<runner-token-see-your-gitlab-runner>
parameter-name=<${var.environment}>-<${var.secure_parameter_store_runner_token_key}>
aws ssm put-parameter --overwrite --type SecureString --name "${parameter-name}" --value ${token} --region "${aws-region}"Once you have created the parameter, you must remove the variable runners_token from your config. The next time your GitLab runner instance is created it will look up the token from the SSM parameter store.
Finally, the runner still supports the manual runner creation. No changes are required. Please keep in mind that this setup will be removed in future releases.
The Auto Scaling Group may be configured with a lifecycle hook that executes a provided Lambda function when the runner is terminated to terminate additional instances that were spawned.
The use of the termination lifecycle can be toggled using the
asg_termination_lifecycle_hook_create variable.
When using this feature, a builds/ directory relative to the root module will
persist that contains the packaged Lambda function.
A few option are provided to access the runner instance:
- Provide a public ssh key to access the runner by setting ``.
- Provide a EC2 key pair to access the runner by setting ``.
- Access via the Session Manager (SSM) by setting
enable_runner_ssm_accesstotrue. The policy to allow access via SSM is not very restrictive. - By setting none of the above, no keys or extra policies will be attached to the instance. You can still configure you own policies by attaching them to
runner_agent_role_arn.
By default the module creates a a cache for the runner in S3. Old objects are automatically removed via a configurable life cycle policy on the bucket.
Creation of the bucket can be disabled and managed outside this module. A good use case is for sharing the cache across multiple runners. For this purpose the cache is implemented as a sub module. For more details see the cache module. An example implementation of this use case can be found in the runner-public example.
Update the variables in terraform.tfvars according to your needs and add the following variables. See the previous step for instructions on how to obtain the token.
runner_name = "NAME_OF_YOUR_RUNNER"
gitlab_url = "GITLAB_URL"
runner_token = "RUNNER_TOKEN"The base image used to host the GitLab Runner agent is the latest available Amazon Linux 2 HVM EBS AMI. In previous versions of this module a hard coded list of AMIs per region was provided. This list has been replaced by a search filter to find the latest AMI. Setting the filter to amzn2-ami-hvm-2.0.20200207.1-x86_64-ebs will allow you to version lock the target AMI.
Below is a basic examples of usages of the module. Regarding the dependencies such as a VPC and SSH keys, have a look at the default example.
module "runner" {
# https://registry.terraform.io/modules/npalm/gitlab-runner/aws/
source = "npalm/gitlab-runner/aws"
aws_region = "eu-west-1"
environment = "spot-runners"
ssh_public_key = local_file.public_ssh_key.content
vpc_id = module.vpc.vpc_id
subnet_ids_gitlab_runner = module.vpc.private_subnets
subnet_id_runners = element(module.vpc.private_subnets, 0)
runners_name = "docker-default"
runners_gitlab_url = "https://gitlab.com"
gitlab_runner_registration_config = {
registration_token = "my-token
tag_list = "docker"
description = "runner default"
locked_to_project = "true"
run_untagged = "false"
maximum_timeout = "3600"
}
}Remove the module from your Terraform code and deregister the runner manually from your Gitlab instance.
Name clashes due to multi-region deployments for global AWS ressources create by this module (IAM, S3) can be avoided by including a distinguishing region specific prefix via the cache_bucket_prefix string respectively via name_iam_objects in the overrides map. A simple example for this would be to set region-specific-prefix to the AWS region the module is deployed to.
module "runner" {
# https://registry.terraform.io/modules/npalm/gitlab-runner/aws/
source = "npalm/gitlab-runner/aws"
aws_region = "eu-west-1"
environment = "spot-runners"
ssh_public_key = local_file.public_ssh_key.content
vpc_id = module.vpc.vpc_id
subnet_ids_gitlab_runner = module.vpc.private_subnets
subnet_id_runners = element(module.vpc.private_subnets, 0)
runners_name = "docker-default"
runners_gitlab_url = "https://gitlab.com"
gitlab_runner_registration_config = {
registration_token = "my-token
tag_list = "docker"
description = "runner default"
locked_to_project = "true"
run_untagged = "false"
maximum_timeout = "3600"
}
overrides = {
name_iam_objects = "<region-specific-prefix>-gitlab-runner-iam"
}
cache_bucket_prefix = "<region-specific-prefix>"
}A few examples are provided. Use the following steps to deploy. Ensure your AWS and Terraform environment is set up correctly. All commands below should be run from the terraform-aws-gitlab-runner/examples/<example-dir> directory. Don't forget to remove the runners manually from your Gitlab instance as soon as your are done.
SSH keys are generated by Terraform and stored in the generated directory of each example directory.
The version of Terraform is locked down via tfenv, see the .terraform-version file for the expected versions. Providers are locked down as well in the providers.tf file.
The examples are configured with defaults that should work in general. The examples are in general configured for the region Ireland eu-west-1. The only parameter that needs to be provided is the GitLab registration token. The token can be found in GitLab in the runner section (global, group or repo scope). Create a file terrafrom.tfvars and the registration token.
registration_token = "MY_TOKEN"
Run terraform init to initialize Terraform. Next you can run terraform plan to inspect the resources that will be created.
To create the runner, run:
terraform applyTo destroy the runner, run:
terraform destroyThis project exists thanks to all the people who contribute.
