Increase memory and cpu for gitlab runner build phase

I have configured my gitlab runner to work with the kubernetes pod. I see that my angular build job gets stuck at below and it keeps going on

Warning: Worker #10 exited unexpectedly (code: null | signal: SIGKILL).
  Current task: {entryPoint: @angular/forms, formatProperty: es2015, processDts: Yes}
  Current phase: compiling

I believe it may be because of a memory/cpu issue. But I am not able to debug as to what would be the issue.

Below are my values.yaml file I used for setting up runners. But below mentioned cpu/memory are not picked up while runners are running.

## GitLab Runner Image
##
## By default it's using gitlab/gitlab-runner:alpine-v{VERSION}
## where {VERSION} is taken from Chart.yaml from appVersion field
##
## ref: https://hub.docker.com/r/gitlab/gitlab-runner/tags/
##
image: 
  registry:<artifactory>/docker-images/gitlab
  image: gitlab-runner
  tag: alpine-v13.1.0


## Specify a imagePullPolicy
## 'Always' if imageTag is 'latest', else set to 'IfNotPresent'
## ref: http://kubernetes.io/docs/user-guide/images/#pre-pulling-images
##
imagePullPolicy: Always

## The GitLab Server URL (with protocol) that want to register the runner against
## ref: https://docs.gitlab.com/runner/commands/README.html#gitlab-runner-register
##
gitlabUrl: <gitlab-url>

## The Registration Token for adding new Runners to the GitLab Server. This must
## be retrieved from your GitLab Instance.
## ref: https://docs.gitlab.com/ce/ci/runners/README.html
##
runnerRegistrationToken: "sdsdsdsdsfsfsfsd"

## The Runner Token for adding new Runners to the GitLab Server. This must
## be retrieved from your GitLab Instance. It is token of already registered runner.
## ref: (we don't yet have docs for that, but we want to use existing token)
##
# runnerToken: ""
#
## Unregister all runners before termination
##
## Updating the runner's chart version or configuration will cause the runner container
## to be terminated and created again. This may cause your Gitlab instance to reference
## non-existant runners. Un-registering the runner before termination mitigates this issue.
## ref: https://docs.gitlab.com/runner/commands/README.html#gitlab-runner-unregister
##
unregisterRunners: true

## When stopping the runner, give it time to wait for its jobs to terminate.
##
## Updating the runner's chart version or configuration will cause the runner container
## to be terminated with a graceful stop request. terminationGracePeriodSeconds
## instructs Kubernetes to wait long enough for the runner pod to terminate gracefully.
## ref: https://docs.gitlab.com/runner/commands/#signals
terminationGracePeriodSeconds: 9000

## Set the certsSecretName in order to pass custom certficates for GitLab Runner to use
## Provide resource name for a Kubernetes Secret Object in the same namespace,
## this is used to populate the /home/gitlab-runner/.gitlab-runner/certs/ directory

Solution

The resources that you provided in your values file are only for the runner itself and not the jobs it produces when a pipeline runs. To increase the cpu/memory requests/limits you need to provide additional configuration. In this additional configuration, you can set the requests and limits in the same way you would with a config.toml file.

You're really just missing something like the following:

runners:
  config: |
    [[runners]]
      executor = "kubernetes"
      [runners.kubernetes]
        cpu_request = 1
        cpu_limit = 2
        memory_request = 2Gi
        memory_limit = 5Gi

There are also a lot more config options in the second link so it might be good to look thru and see if there's any additional options that would help out.
