Gitlab-CI with Docker executor /usr/bin/bash: line 90: git: command not found

Question

I have a local GitLab server and gitlab-ci runner with Docker executor.

I want to use gitlab-ci to build (for the first stage) my Maven project. Since I use buildnumber-maven-plugin I added a Git service to my gitlab-ci.yml like this:

image: maven:latest

services:
  - alpine/git:latest

# Cache goes here
cache:
  paths:
    - .m2/repository
    - frontend-app/node_modules/

# ENV variables goes  here

# Before script goes here

# Stages definition goes here
stages:
  - build

# Build stage
build:
  stage: build
  before_script:
    - mvn --version
    - git --version
  script:
    - mvn clean install --settings .ci/settings.xml
  artifacts:
    paths:
      - backend-app/target/*.jar

But when git --version is executed I got command not found error. This is my complete GitLab CI console log:

Answer 1

If you'd like, you can install git in your maven container. Example (stub) .gitlab-ci.yml:

image: maven:latest

myjob:
  script:
  - yum install -y git
  - git --version

From the CI job log:

$ git --version
 git version 1.8.3.1

Answer 2

A service is another docker container running during your job (a database for example). The docker image alpine/git:latest is not a service, it is used to execute a git command. You can see in your logs that git is called without a command.

Instead of using a service, you should use a docker image with git installed in it to run your job. This way, your script will be able to call git.

Answer 3

The error is occurring, because the git is not available on the runner which picked up your build for execution.

As discussed in previous posts, using services is not efficient.

services:
  - alpine/git:latest 

And also, installing git every-time on your image is time consuming and resource heavy.

myjob:
  script:
  - yum install -y git
  - git --version

So, the most efficient approach is to use the image with git installed upfront and perform your git task.

Below is my example, where I am using an image of alpine/git from dockerhub https://hub.docker.com/r/alpine/git and executing my job on a container launched from this image.

create-git-tag:
  image: alpine/git
  stage: tag
  script:
    - git --version
   

Answer 4

I had a similar issue when working to deploy a Go app to AWS using GitLab CI.

Here's the error code I got:

$ echo "Check the go version"
Check the go version
$ go version
/bin/bash: line 128: go: command not found
Cleaning up project directory and file based variables 00:00
ERROR: Job failed: exit code 1

Here's how I fixed it:

The issue was that I did not specify an image (image: golang:latest) for the job (compile job):

stages:
  - test
  - build
  - deploy

format:
  stage: test
  image: golang:latest
  script:
    - go fmt $(go list ./... | grep -v /vendor/)
    - go vet $(go list ./... | grep -v /vendor/)
    - go test -race $(go list ./... | grep -v /vendor/)  # Test code

compile:
  stage: build
  script:
    - echo "Check the go version"
    - go version  # Display the go version
    - go get -d -v   # Get all go dependencies
    - mkdir -p mybinaries  # Create binaries directory
    - go build -o -v mybinaries ./...  # Build go application and save to a directory
  artifacts:
    paths:
      - mybinaries
  environment:
    name: development
  only:
    - dev

All I had to do was to specify an image (image: golang:latest) for the job (compile):

stages:
  - test
  - build
  - deploy

format:
  stage: test
  image: golang:latest
  script:
    - go fmt $(go list ./... | grep -v /vendor/)
    - go vet $(go list ./... | grep -v /vendor/)
    - go test -race $(go list ./... | grep -v /vendor/)  # Test code

compile:
  stage: build
  image: golang:latest
  script:
    - echo "Check the go version"
    - go version  # Display the go version
    - go get -d -v   # Get all go dependencies
    - mkdir -p mybinaries  # Create binaries directory
    - go build -o -v mybinaries ./...  # Build go application and save to a directory
  artifacts:
    paths:
      - mybinaries
  environment:
    name: development
  only:
    - dev

I could also specify the image globally (image: golang:latest) at the top of the script:

image: golang:latest

stages:
  - test
  - build
  - deploy

format:
  stage: test
  script:
    - go fmt $(go list ./... | grep -v /vendor/)
    - go vet $(go list ./... | grep -v /vendor/)
    - go test -race $(go list ./... | grep -v /vendor/)  # Test code

compile:
  stage: build
  script:
    - echo "Check the go version"
    - go version  # Display the go version
    - go get -d -v   # Get all go dependencies
    - mkdir -p mybinaries  # Create binaries directory
    - go build -o -v mybinaries ./...  # Build go application and save to a directory
  artifacts:
    paths:
      - mybinaries
  environment:
    name: development
  only:
    - dev
