首先说说安装步骤

1、安装版本
gitlab-runner-0.36.1.tgz

cat ./gitlab-runner/values.yaml |grep -v "#"|sed -e '/^$/d'
imagePullPolicy: IfNotPresent
gitlabUrl: http://101.43.196.155:32080/
runnerRegistrationToken: "Woq_Drxy-SSy1kQzJBZT"
terminationGracePeriodSeconds: 3600
concurrent: 10
checkInterval: 10
rbac:
  create: true
  resources: ["pods", "pods/exec", "secrets", "configmaps", "pods/attach"]
  verbs: ["get", "list", "watch", "create", "patch", "delete", "update"]
  rules: []
  clusterWideAccess: false
  podSecurityPolicy:
    enabled: false
    resourceNames:
    - gitlab-runner
metrics:
  enabled: true
  portName: metrics
  port: 9252
  serviceMonitor:
    enabled: false
service:
  enabled: false
  type: ClusterIP
runners:
  config: |
    [[runners]]
      [runners.kubernetes]
        namespace = "{{.Release.Namespace}}"
        image = "ubuntu:16.04"
  tags: "k8s-runner,k8s"
  privileged: true
  cache: {}
  builds: {}
  services: {}
  helpers: {}
securityContext:
  runAsUser: 100
  fsGroup: 65533

  [[runners]]
    url = "https://gitlab.com/"
    executor = "docker"
    privileged = true
    [runners.docker]
      tls_verify = false
      image = "docker:24.0.7"
      privileged = true
      disable_cache = false
      volumes = ["/var/run/docker.sock:/var/run/docker.sock","/cache"]
    [runners.cache]
      Insecure = false

cat ./gitlab-runner/values.yaml |grep -v "#"|sed -e '/^$/d'

helm install  gitlab-runner --namespace kube-ops ./gitlab-runner

这个问题经过排查发现 gitlab-runner 无法调用docker.sock

需要修改gitlab.toml 配置文件

有两个方法可以修改

1、gitlab-runner 创建后登录 gitlab-runner 修改 config.toml 配置文件

[root@master gitlab-runner]# kubectl get po -n kube-ops
NAME                                           READY   STATUS    RESTARTS   AGE
gitlab-runner-gitlab-runner-5fb9cfff9c-kfbkb   1/1     Running   0          19m
[root@master gitlab-runner]# kubectl exec -it -n kube-ops gitlab-runner-gitlab-runner-5fb9cfff9c-kfbkb -- /bin/bash
Defaulted container "gitlab-runner-gitlab-runner" out of: gitlab-runner-gitlab-runner, configure (init)
bash-5.0$ cat /home/gitlab-runner/.gitlab-runner/config.toml 
listen_address = ":9252"
concurrent = 10
check_interval = 10
log_level = "info"

[session_server]
  session_timeout = 1800

[[runners]]
  name = "gitlab-runner-gitlab-runner-5fb9cfff9c-kfbkb"
  url = "http://101.43.196.155:32080/"
  token = "FbCFy9T5anUR23tMbJRQ"
  executor = "kubernetes"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.kubernetes]
    host = ""
    bearer_token_overwrite_allowed = false
    image = "ubuntu:16.04"
    namespace = "kube-ops"
    namespace_overwrite_allowed = ""
    privileged = true
    service_account_overwrite_allowed = ""
    pod_annotations_overwrite_allowed = ""
    [runners.kubernetes.affinity]
    [runners.kubernetes.pod_security_context]
    [runners.kubernetes.build_container_security_context]
      [runners.kubernetes.build_container_security_context.capabilities]
    [runners.kubernetes.helper_container_security_context]
      [runners.kubernetes.helper_container_security_context.capabilities]
    [runners.kubernetes.service_container_security_context]
      [runners.kubernetes.service_container_security_context.capabilities]
    [runners.kubernetes.volumes]
    [runners.kubernetes.dns_config]
    [runners.kubernetes.container_lifecycle]
  [[runners.kubernetes.volumes.host_path]]
        name = "docker"
        mount_path = "/var/run/docker.sock"

第二个方法

解压 gitlab-runner-0.36.1.tgz 加压安装包在当前目录会生成 gitlab-runner

在 gitlab-runner 目录的 gitlab-runner/templates/configmap.yaml 文件内调整如下

然后重新安装

 helm install  gitlab-runner --namespace kube-ops ./gitlab-runner

[root@master gitlab-runner]# cat ./gitlab-runner/templates/configmap.yaml 
apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ include "gitlab-runner.fullname" . }}

    heritage: "{{ .Release.Service }}"

      export GOOGLE_APPLICATION_CREDENTIALS="/secrets/gcs-application-credentials-file"
    else
      if [[ -f /secrets/gcs-access-id && -f /secrets/gcs-private-key ]]; then
        export CACHE_GCS_ACCESS_ID=$(cat /secrets/gcs-access-id)
        # echo -e used to make private key multiline (in google json auth key private key is oneline with \n)
        export CACHE_GCS_PRIVATE_KEY=$(echo -e $(cat /secrets/gcs-private-key))
      fi
    fi

    if [[ -f /secrets/azure-account-name && -f /secrets/azure-account-key ]]; then
      export CACHE_AZURE_ACCOUNT_NAME=$(cat /secrets/azure-account-name)
      export CACHE_AZURE_ACCOUNT_KEY=$(cat /secrets/azure-account-key)
    fi

    if [[ -f /secrets/runner-registration-token ]]; then

    if [[ ! -z "$CI_SERVER_TOKEN" && "{{ default 1 .Values.replicas }}" -ne "1" ]]; then
      echo "Using a runner token with more than 1 replica is not supported."
      exit 1
    fi

    # Register the runner

    fi
