----------------------------------
Summary: Docker environment variables must be able to contain the
equal sign
Key: MESOS-4587
URL: https://issues.apache.org/jira/browse/MESOS-4587
Project: Mesos
Issue Type: Bug
Components: docker
Affects Versions: 0.25.0
Reporter: Martin Tapp
Priority: Minor
Note: Affects 0.26 and 0.27.
The Jupyter Docker all-spark-notebook uses equal sign ('=') in Docker ENV
declarations (for instance,
https://github.com/jupyter/docker-stacks/blob/master/all-spark-notebook/Dockerfile#L51).
This causes a mesos Unexpected Env format for 'ContainerConfig.Env' error.
The problem is the tokenization code at
https://github.com/apache/mesos/blob/21e080c5ae6ef03556c7a2b588e034a916c7a05a/src/docker/docker.cpp#L386
which needs to only look at the first equal sign. Docker ENV declarations can
also be empty.
