Getting error "Already have image (with digest): gcr.io/cloud-builders/docker" while trying Gitlab CICD

Question

I am trying to use Gitlab CI/CD with Cloud Build and Cloud Run to deploy a Flask application.

I am getting an error

Dockerfile

ADD . /app

RUN ls -la data/
RUN pwd

RUN pip install -r requirements.txt

Trying other solutions I tried to prune dockers from the VM which was used for Runner in the CICD settings, I have experimented from a test repo and it worked completely, I am getting this error while replicating it on a new repo. with changed the name to fts_im. I haven't deleted the previous build and deployed app from cloud build and cloud run, because while using the previous repo I experimented build multiple time all successful.

As per this document Dockerfile should present in the same directory where the build config file is,

Run below command check if Dockerfile present in current directory or not

docker build -t docker-whale

If Dockerfile is present in the same directory where the build config file is, then review this documentation to ensure the correct working directory has been set in the build config file.

Make sure GitLab CI/CD is set up correctly and configured to run on the current branch.

Also you have to specify the full path of the Dockerfile in cloudbuild.yaml file

The name of the file should be Dockerfile and not **.**Dockerfile. The file should not have any extension. check the Dockerfile is named correctly .

Check you have not misspelled image name, I can see 2 different image names gcr.io/$PROJECT_ID/fts-im and gcr.io/$PROJECT_ID/fts_im, I’m not sure whether they are 2 different image or you misplaced _(underscore) with -(Hyphen).
