環境

  • Red Hat Enterprise Linux (RHEL) 7.4
  • Red Hat OpenShift Linux Client (oc) v3.6.173.0.21

問題

  • Bash completion for oc command does not work. Pressing tab key after oc does not show openshift client command parameters.

解決策

  • When deploying the Openshift Linux client from tar.gz archive, user should manually generate the completion script for bash with the following command:
# oc completion bash >>/etc/bash_completion.d/oc_completion
  • The output file can be saved in user local directory and sourced from ~/.bashrc file as well.

Note: Ensure bash-completion package is already present on the system in order to get oc bash completions working.

原因

OpenShift Linux Client /usr/bin/oc can be installed from atomic-openshift-clients.rpm package or simply extracted from tar.gz archive to any user directory.

The package version contains manual pages and bash completion script which is installed in default location: /etc/bash_completion.d/oc while only a single executable file is available in the archive version.

診断手順

With autocompletion enabled the shell presents oc supported commands:

# oc 
adm              completion       describe         get              new-app          process          rsync            tag
annotate         config           edit             idle             new-build        project          run              types
apply            convert          env              import           new-project      projects         scale            version
attach           cp               exec             import-image     observe          proxy            secrets          volumes
auth             create           explain          label            options          replace          serviceaccounts  whoami
autoscale        debug            export           login            patch            rollback         set              
cancel-build     delete           expose           logout           policy           rollout          start-build      
cluster          deploy           extract          logs             port-forward     rsh              status
