I have a problem where the application code is developed and built in vendor premises and only code binary is sent in the form of docker image and uploaded to Nexus repository. Now, I need to create a deployment pipeline in GitLab which will be triggered as soon as a new image is uploaded to nexus.
Please suggest any solution.
I have tried to create a parent child pipeline where I am trying to check the HTTP resonse status from Nexus through curl request, trigger the child pipeline only when the status is 200. The parent pipeline can be configured as a scheduled pipeline which will check the image availability on a regular interval.
Parent yml:
stages:
- build
- trigger_child
build:
stage: build
script:
- echo "img_status=`curl -s -o /dev/null -w "%{http_code}" https://www.google.com`" >> build.env
artifacts:
reports:
dotenv: build.env
trigger_child:
stage: trigger_child
trigger:
include:
- local: App/.gitlab-ci.yml
strategy: depend
needs:
- job: build
artifacts: true
rules:
- if: $img_status == "200"
when: always
Child yml:
stages:
- deploy
deploy:
stage: deploy
script:
- echo "This job deploys something new"
