Script command using ":" causing error in .gitlab-ci.yml execution

Question

Below my .gitlab-ci.yml file:

image: docker:latest

services:
    - docker:dind

stages:
    - deploy_dev_env

Deploy DEV Environment:

    stage: deploy_dev_env

    script:

        - curl -v -H "Content-Type: multipart/form-data" -X PUT -F uploadInput=@schema/schema.xml -F overwrite=true -F xmlaEnabledFlag=true -F parameters="DataSource=outputDS" -F parameters="EnableXmla=true" -u $PENTAHO_DEPLOY_USER:$PENTAHO_DEPLOY_PASSWORD http://$PENTAHO_HOST/pentaho/plugin/data-access/api/datasource/analysis/catalog/sca

This very simple script is causing an error because the colons(:) in the "Content-Type: multipart/form-data" piece.

Running the CI Lint in the script I get the following:

Status: syntax is incorrect

jobs:deploy dev environment:script config should be a string or an array containing strings and arrays of strings

If I replace "Content-Type: multipart/form-data" by "Content-Type multipart/form-data" (removed the ":"), I get I correct syntax for my .gitlab-ci.yml file.

Is this a bug or should I re-write my curl command in a different way ?

Docs warn about special characters in yaml script:

Note: Sometimes, script commands will need to be wrapped in single or double quotes. For example, commands that contain a colon (:) need to be wrapped in quotes so that the YAML parser knows to interpret the whole thing as a string rather than a “key: value” pair. Be careful when using special characters: :, {, }, [, ], ,, &, *, #, ?, |, -, <, >, =, !, %, @, `.

One of the option would be to use yaml block scalar

Deploy DEV Environment:
    stage: deploy_dev_env
    script: >
        curl -v -H "Content-Type: multipart/form-data" -X PUT -F uploadInput=@schema/schema.xml -F overwrite=true -F xmlaEnabledFlag=true -F parameters="DataSource=outputDS" -F parameters="EnableXmla=true" -u $PENTAHO_DEPLOY_USER:$PENTAHO_DEPLOY_PASSWORD http://$PENTAHO_HOST/pentaho/plugin/data-access/api/datasource/analysis/catalog/sca

or use some other way to escape colon in yaml.

Based on your answer and link for the docs, I've used single quotes to wrap the command. It worked like a charm. — Kleyson Rios, Mar 26 '20 at 12:44

I faced this issue due to yaml syntax before and the workaround i found was

Store the "Content-Type: application/json" as an environment variable in the CICD settings for example

Key: HEADER
Value: Content-Type: application/json

and in your script

- curl -v -H "$HEADER" -X PUT -F uploadInput=@schema/schema.xml -F overwrite=true -F xmlaEnabledFlag=true -F parameters="DataSource=outputDS" -F parameters="EnableXmla=true" -u $PENTAHO_DEPLOY_USER:$PENTAHO_DEPLOY_PASSWORD http://$PENTAHO_HOST/pentaho/plugin/data-access/api/datasource/analysis/catalog/sca

It's an option. Thanks. – Kleyson Rios Mar 26 '20 at 12:43 — Kleyson Rios, Mar 26 '20 at 12:43

After going through several options, I found below simple solution Use like this,


Content_Type="Content-Type:"
export RESULT="$(echo "$Content_Type" multipart/form-data)"
echo "Result is " $RESULT

Use $RESULT as variable there
