GitLab CI/CD not taking latest code changes - docker

Question

So I have used GitLab CI/CD to deploy changes to private docker hub repo and using Digital Ocean droplet to run the server using docker but the changes are not being reflected in the docker container running on digital ocean. Here's the config file.
variables:
IMAGE_NAME: codelyzer/test-repo
IMAGE_TAG: test-app-1.0
stages:
- test
- build
- deploy
run_tests:
stage: test
image:
node:16
before_script:
- npm install jest
script:
npm run test
build_image:
stage: build
image: docker:20.10.16
services:
- docker:20.10.16-dind
variables:
DOCKER_TLS_CERTDIR: "/certs"
before_script:
- docker login -u $REGISTRY_USER -p $REGISTRY_PASS
script:
- docker build -t $IMAGE_NAME:$IMAGE_TAG .
- docker push $IMAGE_NAME:$IMAGE_TAG
deploy:
stage: deploy
before_script:
- chmod 400 $SSH_KEY
script:
- ssh -o StrictHostKeyChecking=no -i $SSH_KEY root#159.89.175.212 "
docker login -u $REGISTRY_USER -p $REGISTRY_PASS &&
docker image prune -f &&
docker ps -aq | xargs docker stop | xargs docker rm &&
docker run -d -p 5001:5001 $IMAGE_NAME:$IMAGE_TAG"

Answer 1

The digital ocean server wasn't fetching the latest image from the repository so I added docker prune as additional step to do.
deploy:
stage: deploy
before_script:
- chmod 400 $SSH_KEY
script:
- ssh -o StrictHostKeyChecking=no -i $SSH_KEY root#159.89.175.212 "
docker login -u $REGISTRY_USER -p $REGISTRY_PASS &&
docker ps -aq | (xargs docker stop || true) | (xargs docker rm || true) &&
docker system prune -a -f &&
docker run -d -p 5001:5001 $IMAGE_NAME:$IMAGE_TAG"
