Render error of a variable with the dash symbol and surrounded with the double-quotes #574
Description
Description
When we try to use dash symbol (-) as a part of the variable name (aka. key) and surround the variable with the double-quotes - docker app binary produces a render error. The problem doesn't appear when we do not use the dash symbol in the variable name, or we use a variable name in the docker-compose.yml file without double-quotes.
I also attached the working examples - see the Annex №4,5,6 and Annex №7,8,9 below.
Steps to reproduce the issue:
- Have the docker-compose file with the following content - see the Annex №1 below.
- Have the parameters.yml file with the following content - see the Annex №2 below.
- Have the parameters.yml file with the following content - see the Annex №3 below.
- Execute the following render command - docker-app-standalone-linux render.
Describe the results you received:
Unfortunately, we've got the following error:
Error: render failed: Action "com.docker.app.render" failed: failed to load Compose file: invalid interpolation format for x-default-placement.placement.constraints.[]: "required variable constraints.node.labels.operating-system\" is missing a value". You may need to escape any $ with another $.
Describe the results you expected:
We expect from docker app binary to render template correctly.
