Environment variables from my project settings not properly working in my pipelines

[kalib]

I am trying to use some environment variables in my bitbucket pipeline scripts and it looks like the variables are not being passed, for example:

- VERSION=${BITBUCKET_TAG:-${BITBUCKET_BRANCH//\//_}-latest}
- IMAGE_NAME="${NEXUS_DOCKER_PRIVATE_REGISTRY_URL}/baseline-service:${VERSION}"
- docker build . -t $IMAGE_NAME --pull --no-cache --label 'GIT_COMMIT_HASH=$BITBUCKET_COMMIT'

In that case, NEXUS_DOCKER_PRIVATE_REGISTRY_URL is my environment variable, but it's not being translated properly:

+ docker build . -t $IMAGE_NAME --pull --no-cache --label 'GIT_COMMIT_HASH=$BITBUCKET_COMMIT'
invalid argument "$NEXUS_DOCKER_PRIVATE_REGISTRY_URL/my-service:feature_pipeline-latest" for "-t, --tag" flag: invalid reference format

Hello @kalib ,

From the error message seems like the IMAGE_NAME variable was not populated correctly. Checking the syntax you have used in IMAGE_NAME, it seems to be correct, and testing on my repository it was correctly presenting the value.

Could you please confirm if the NEXUS_DOCKER_PRIVATE_REGISTRY_URL has not any typo when you created it in your repository settings/workspace settings ?

One thing you can also do for troubleshooting is to print the variables using echo after you have created them and see if the value is correct, like below :

- VERSION=${BITBUCKET_TAG:-${BITBUCKET_BRANCH//\//_}-latest}
- echo $VERSION
- IMAGE_NAME="${NEXUS_DOCKER_PRIVATE_REGISTRY_URL}/baseline-service:${VERSION}"
- echo $IMAGE_NAME
- echo $NEXUS_DOCKER_PRIVATE_REGISTRY_URL

Would you please try the above and let us know the output ?

Thank you, @kalib .

Kind regards,

Thanks, this method for validation worked for me as well. Thanks, it will make it way easier for troubleshooting.

Hey @kalib ,

Awesome! It's indeed way easier to investigate when printing the variable value with echo. Do let us know in case you have any other questions.

Kind regards,
