.gitlab-ci.yml · main · Nana Janashia / gitlab-cicd-crash-course · GitLab
Main idea:
1. .gitlab-ci.yml will host the classical 3 stages which are
a. test
b. build
c. deploy
2. build will use a docker image and service to build and push the docker image to docker hub
3. deploy will ssh to the target machine, kill existing docker image, run the specific docker image
