Docker in Jenkins pipeline fails to run due to invalid environment variable: =

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'. at org.jenkinsci.plugins.docker.workflow.client.DockerClient.run(DockerClient.java:128) at

Ok solved it.

Basically, there was an empty environment variable set in Jenkins. Removed the empty variable and it worked!
