Horizontal Discovery - Failed Exploring CI Pattern. Check Pattern Docker Pattern Log HereIssue Symptoms Horizontal Discovery fails when discovering Docker Virtualization Application. Discovery logs shows "Failed Exploring CI Pattern. Check Pattern Docker Pattern Log Here": When you click on the link "Here", Horizontal Discovery Log shows the pattern failed at step "guard against unrunnable commands" Release From Jakarta Cause This is due to missing credential privileges being used by Discovery. For Docker Virtualization discovery we require the credential to be root or the credential should be a member of the docker group. This is detailed in our product documentation here under the section User Privileges. Resolution Either use a root credential or add the user credential to the docker group by logging into the Linux server targeted by Discovery and running the command "sudo usermod -a -G user_name docker". This will add Linux user with name "user_name" to the group "docker".
