how to use it:

$ che action workspace-ssh :workspaceName
$ che action workspace-ssh workspaceId

If you need to connect with ssh utility, you may use get-ssh-data

$ che action get-ssh-data <workspaceName>
SSH_IP=192.168.65.2
SSH_PORT=32900
SSH_USER=user
SSH_PRIVATE_KEY='
-----BEGIN RSA PRIVATE KEY-----
content
-----END RSA PRIVATE KEY-----

'

it requires current master or nightly build from 05th november

Update che-mount to not enter any docker image password (or username)

(it requires to build che-action, che-dir and che-mount images)

on macos :

to connect to local che

docker run --cap-add SYS_ADMIN --device /dev/fuse -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):/mnthost -ti codenvy/che-mount:nightly <workspace-name>

with remote server (that has workspace ssh keys enabled):

docker run --cap-add SYS_ADMIN --device /dev/fuse -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):/mnthost -ti codenvy/che-mount:nightly <workspace-name> --url=https://<myserver> --user=<my-email> --password <my-password>
