dynamic variable by command
curl http://test.com
I try to pass variables by this solution below but It's show as string "$(curl http://test.com)" how to solve it
.test
variables:
SERVER : $(curl http://test.com)
As in here, you can try and assign the variable in a before_script step:
before_script:
- export SERVER=$(cat .nvmrc)
Then you can use $SERVER in other steps of your pipeline.
That was also suggested in issue 34202 (Allow setting variable to a contents of a file).

Given the following very simple .gitlab-ci.yml pipeline:
---
variables:
KEYCLOAK_VERSION: 20.0.1 # this should be populated from reading a file from the repo...
stages:
- test
build:
stage: test
script:
- echo "$KEYCLOAK_VERSION"
As you might see, this simply outputs the value of KEYCLOAK_VERSION defined in the variables section.
Now, the Git repository contains a env.properties file with KEYCLOAK_VERSION=20.0.1 as content. How would I read the variable from that file and use it in the GitLab pipeline?
The documentation mentions import but this seems to be using YAML files.
To read variables from a file you can use the source or . command.
script:
- source env.properties
- echo $KEYCLOAK_VERSION
Attention:
One reason why you might not want to do it this way is because whatever is in env.properties will be run in your shell, such as rm -rf /, which could be very dangerous.
Maybe you can take a look here for some other solutions.
I have a simple pipeline with one job to test bash scripts. The pipeline as follow:
image: alpine/git
stages:
- test_branching
test_branch:
stage: test_branching
before_script:
- mkdir -p .common
- wget https://x.x.x.x/branching.sh > .common/test.sh && chmod +x .common/test.sh
- source .common/test.sh
script:
- test_pipe
- echo "app version is ${app_version}"
The bash script as follow:
#!/bin/sh
function test_pipe () {
app_version="1.0.0.0-SNAPSHOT"
}
The problem is that the pipeline for whatever reason does not recognize the function inside the script. The logs are:
...
$ test_pipe
/scripts-1050-417479/step_script: eval: line 180: test_pipe: not found
Does anybody know what happend with this?? I miss a lot Jenkins shared libraries, gitlab does not have it, also gitlab does not have the function to include scripts inside yml files.
I dont want to use multiproject pipeline, I need to do it at this way. This is only an example of a more complicated pipeline logic.
Thanks in advance
As the documentation states before_script is just concatenated together with script and run on a single shell. The script you are downloading does not define test_pipe.
... gitlab does not have the function to include scripts inside yml
files.
It does, just use the YAML multiline literal syntax with |, e.g.:
script:
- |
echo "this"
echo "is"
echo "an \
example"
Here's what I am trying to do.
in .gitlab-ci:
Check schedules pass:
stage: check
image: ${myimage}
script:
- MY_CI_VAR=aVeryLongVariable
- echo "$MY_SCHEDULE_VAR"
In schedules:
Which is not working.
The reason I want to do this is for picking different variable (out of many in the job) on each schedule.
Yes, it is possible to use variables within other variables. This feature was released in GitLab 14.3.
However, since you are using GitLab 13.x, this feature won't be available to you.
You may be able to get around this limitation by using a static value and altering your job script accordingly.
myjob:
before_script: |
if [[ "$SCHEDULE_VAR" == "abc" ]]; then
export FOO="$MY_CI_VAR"
fi
# ...
In versions of GitLab < 14.3 you can still make use of other variables within variables, but instead by using $$ to preserve variables from evaluation.
Example from the docs:
variables:
FLAGS: '-al'
LS_CMD: 'ls "$FLAGS" $$TMP_DIR'
script:
- 'eval "$LS_CMD"' # Executes 'ls -al $TMP_DIR'
I have a gitlab yaml file for running certain jobs. In the variables part, I have declared certain variables with values and when I try to use it in another variable formation, it is actually generating but not fetching in the later part of job execution.
Code tried is as below:
variables:
env: "prod"
user: "test"
region: "us-east"
var1: '$env-$user-$region'
As suggested in one forum to include var1 formation in before_script script part. I tried it, but it was also not returning the var1 value correctly.
Any help will be appreciated.
At the bottom of this section of the official documentation, they describe using variables within variables:
You can use variables to help define other variables. Use $$ to ignore a variable name inside another variable:
variables:
FLAGS: '-al'
LS_CMD: 'ls $FLAGS $$TMP_DIR'
script:
- 'eval $LS_CMD' # Executes 'ls -al $TMP_DIR'
I was able to follow this pattern, and additionally I was combining variables in the script: step with a command such as:
script:
- APP_NAME=$APP_NAME-$VERSION
I have a yml file used by an Azure pipeline for configuration.
variables:
CHANGE_URL : $(System.PullRequest.SourceRepositoryURI)/pull/$(System.PullRequest.PullRequestNumber)
The resulting variable CHANGE_URL is: https://github.com/username/project-boilerplate.git/9
The values are coming from Azure's predefined system variables. I'm trying to remove the '.git' from this string. I tried
CHANGE_URL : sed 's/...$//' <<< $(System.PullRequest.SourceRepositoryURI) but that did not work. I'm not sure how much control I have with yml files.
you need to have a script step that does that:
- bash: |
value=$(sed 's/...$//' <<< $(System.PullRequest.SourceRepositoryURI))
echo "##vso[task.setvariable variable=CHANGE_URL]$value"
and then in your subsequent steps you'd have a variable CHANGE_URL with the value you needed
