Question

i have an angular app adn i have wrote a pipline for it like this:

image: node:16.13.2
variables:
  DOCKER_HOST: myurl
  GIT_STRATEGY: clone
  TAG_LATEST: latest
  TAG_COMMIT: $CI_COMMIT_REF_NAME-$CI_COMMIT_SHORT_SHA

.login_into_nexus: &login_into_nexus
  - echo "Login Into Nexus...."
  - docker login -u $NEXUS_USERNAME -p $NEXUS_PASS $NEXUS_URL

services:
  - docker:dind

stages:
  - build

install-dependency:
  stage: .pre
  script:
    - npm i --prefer-offline # install dependencies
  cache:
    key: "{$CI_JOB_NAME}"
    paths:
      - node_modules
    policy: pull-push
  artifacts:
    paths:
      - node_modules/

build:
  stage: build
  needs:
    - job: install-dependency
      artifacts: true
  script:
    - npm run build:aot
  rules:
    - if: '$CI_PIPELINE_SOURCE == "push"'
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"'
    - if: '$CI_PIPELINE_SOURCE != "push" && $CI_PIPELINE_SOURCE != "merge_request_event" && $CI_COMMIT_REF_NAME == "master"'
    - if: '$CI_PIPELINE_SOURCE != "push" && $CI_PIPELINE_SOURCE != "merge_request_event" && $CI_COMMIT_REF_NAME == "develop"'

as seen above the pipeline downloads node modules from my nexus and installs it in the install-dependency job

i also have 5 runners on this project and each one of them can pick the job. but each runner saves the cache for itself and when i run the pipeline on another branch it wont use the saved cache on the other branch

my gitlab version is: 13.3.5-ee

Answer 1

You must enable distributed caching in order for all your runners to share the same cache. Otherwise, the default is that the cache is local to the runner.
