[ https://issues.jboss.org/browse/JBDS-3739?page=com.atlassian.jira.plugin.... ] Marián Labuda commented on JBDS-3739: ------------------------------------- For me docker connection is not working neither. At first I thought it's happening only after restart, but also on new connection (just created) by first run of CDK in devstudio, I cannot work with docker connection. I am running nightly CDK 2.1 with box rhel-7-cdk-vagrant-scratch-7.2.02062016-1.x86_64.vagrant-virtualbox.box and in devstudio Verified in devstudio with build id: GA-v20160603-0516-B5506.
