Eclipse CHE

Sadly, CHE is not dedicated to greatly inspiring revolutionary leader Che Guevara, but to the city of Cherkasy (Ukraine) where most of the development is done.

docker run eclipse/che start

Since I run from a VirtualBox VM on my Windows PUEAH host, I get this:

INFO: Welcome to Eclipse Che!
INFO: 
INFO: You are missing a mandatory parameter:
INFO:    1. Mount 'docker.sock' for accessing Docker with unix sockets.
INFO:    2. Or, set DOCKER_HOST to Docker's location (unix or tcp).
INFO: 
INFO: Mount Syntax:

INFO:

INFO:    2. You passed '--user uid:gid' with bad values.
INFO:    3. Your firewall is blocking TCP ports for accessing Docker daemon.

now I try running this

[centos@localhost ~]$ docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock eclipse/che start

INFO:                       -v :/data/backup
INFO:                          eclipse/che start

so I do

mkdir chedata
docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v /home/centos/chedata:/data eclipse/che start


if you run "docker run --help", you learn that "-it" means "interactive tty" , "--rm" means "--rm , the container is removed when it exits", -v bind mount a volume


at this point I still get an error:

ERROR: Try 'docker run  eclipse/che info --network' for more tests.

so I run

docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v /home/centos/chedata:/data eclipse/che info --network

and I get this

Probably I have to work a little on my VM network settings ... maybe some other time...
