I'm trying to run a docker container in a jenkins pipeline like so:
agent {
docker {
image 'indiehosters/git'
reuseNode true
}
}
but the pipeline fails to run. It seems an invalid environment variable is being set when the docker container is run.
I'm using Jenkins version 2.65, Docker pipeline plugin 1.11, Pipeline plug 2.5
The stacktrace from the Jenkins console:
java.io.IOException: Failed to run image 'indiehosters/git'. Error: invalid argument "=" for e: invalid environment variable: =
See 'docker run --help'.

There are two ways to run Jenkins build steps in such an image. One is to include a Java runtime and Jenkins agent JAR file inside the image, and add a Docker cloud using the Docker plugin. Then the entire agent runs wholly inside the image, so any builds tied to that cloud label can assume a particular environment.
Pipeline is designed to easily use Docker images as the execution environment for a single Stage or the entire Pipeline. Meaning that a user can define the tools required for their Pipeline, without having to manually configure agents. Practically any tool which can be packaged in a Docker container.
Compose Configuration (Linux or macOS) Add a group docker if it does not exist, and add jenkins user to the docker group, e.g. groupadd docker && usermode -aG docker 'jenkins' . Adjust permissions on the docker. sock file so that jenkins user can access it, e.g. chmod 777 /var/run/docker.
Install the above two plugins using Jenkins' “Plugin Manager”. Creating and configuring Jenkins job to build images from Dockerfile: Create a new Jenkins job (say “Build Docker Image“) which will use CloudBees Docker Build and Publish plugin to build images from Dockerfile and push it on DockerHub.
Ok solved it.
Basically, there was an empty environment variable set in Jenkins. Removed the empty variable and it worked!
