问题
I want to kick off an npm deployment when a tag, that looks like a semantic version, is pushed, e.g. v1.2.3. I see that the tag name is in the TRAVIS_TAG environment variable and that I can specify an on: condition, which "can be any Bash condition". I have no idea what to write here and how to debug it.
- provider: npm
on:
tags: true
all_branches: true
condition: ???
Ideally, I would like to not bother with Bash at all - I would like the condition to execute a Node.js script and then decide whether to deploy or not depending on the node exit code. How can I do that?
回答1:
Simplest way would still be with bash, this example will deploy only if tag name matches the regex "release.*":
on:
tags: true
all_branches: true
condition: "$TRAVIS_TAG =~ ^release.*$"

eshizari's answer didn't work for me. This is the approach that I'm using instead:
on:
all_branches: true
condition: $TRAVIS_TAG =~ ^v[0-9]+\.[0-9]+\.[0-9]+
