Run Lens on docker Very handy for dev testing Works on Mac – https://docs.docker.com/installation/mac/ https://docs.docker.com/installation/mac/ – http://boot2docker.io/ http://boot2docker.io/ Build the Lens docker image – tools/scripts/build-docker.sh – Required only once unless the docker image is changed Run the container – tools/scripts/run-docker.sh mounts your incubator-lens git home to /opt/lens into the docker container Exports the lens server and client dist into the LENS_HOME and LENS_CLIENT env
