README

backplane-cli

backplane-cli is a CLI tool to interact with backplane api.

Installation

Go should be installed in your local system with version 1.19

Option 1: Download from release

Download the latest binary from the GitHub releases page.

For example, to download the binary on Linux:

$ wget https://github.com/openshift/backplane-cli/releases/download/v0.1.1/ocm-backplane_0.1.1_Linux_x86_64.tar.gz
$ tar -xvzf ocm-backplane_0.1.1_Linux_x86_64.tar.gz
$ chmod +x ocm-backplane
$ mv ocm-backplane $GOBIN

Option 2: Build from source

First clone the repository somewhere in your $PATH. A common place would be within your $GOPATH.

Example:

$ mkdir $GOPATH/src/github.com/openshift
$ cd $GOPATH/src/github.com/openshift
$ git clone git@github.com/openshift/backplane-cli.git

$ make build

This command will build the backplane-cli binary, named ocm-backplane. This binary will be placed in $PATH. As the binary has prefix ocm-, it becomes a plugin of ocm, and can be invoked by ocm backplane.

For more information about ocm plugins, please refer https://github.com/openshift-online/ocm-cli#extend-ocm-with-plugins

Configuration

The configuration file of backplane-cli is expected to be located at $HOME/.config/backplane/config.json.

Setup bash/zsh prompt

To setup the PS1(prompt) for bash/zsh, please follow these instructions.

Login

Example

In this example, we will login to a cluster with id 123456abcdef in production environment, and we have the OCM client environment setup like this.

• Run backplane login in another terminal.

  $ ocm backplane login <cluster>
  

• Run oc command to access the target cluster.

  $ oc whoami
  system:serviceaccount:openshift-backplane-srep:1234567
  

• To login to the Management cluster for HyperShift (or) the managing Hive shard of normal OSD/ROSA cluster

  $ ocm backplane login <cluster> --manager
  

• To login to the Service Cluster of a HyperShift hosted cluster or the Management Cluster

  $ ocm backplane login <cluster> --service
  

Login to multiple clusters

Logging into multiple clusters via different terminal instances.

• How to log into the first cluster

  $ ocm backplane login <cluster-id-1> --multi
  $ export KUBECONFIG= <cluster-id-1-kube-config-path>
  

• How to log into the second cluster

  $ ocm backplane login <cluster-id-2> --multi
  $ export KUBECONFIG= <cluster-id-2-kube-config-path>
  

Console

• Login to the target cluster via backplane as the above.

• Run the below command and it will launch the console of the current logged in cluster.

  $ ocm backplane console
  --> Console will be available at http://127.0.x.x:xxxx
  

• Follow the above link http://127.0.x.x:xxxx to access console.

  Open in browser

  You can directly open the console in browser by adding flag -b or setting environment variable BACKPLANE_DEFAULT_OPEN_BROWSER=true. Example,

  When running this command, it will open the console in the browser automatically.

  $ ocm backplane console -b
  

  Or set the environment variable

  $ export BACKPLANE_DEFAULT_OPEN_BROWSER=true
  
  $ ocm backplane console
  

  Optionally, you can also load the enabled console plugin

  $ ocm backplane console -plugins
  

  Note: Load the console plugin from backplane-cli is not sufficient to access the console plugin, backplane-api to expose the console plugin service explicitly is needed.

Cloud Console

• Login to the target cluster via backplane as the above.

• Run the below command and it will launch the cloud console of the current logged in cluster.

  $ ocm backplane cloud console
  Console Link:
  Link: https://xxxxx
  

• Follow the above link to access the console.

  Open in browser

  You can directly open the console in the browser by adding flag -b or setting the environment variable BACKPLANE_DEFAULT_OPEN_BROWSER=true.

  When running this command, it will open the console in the browser automatically.

  $ ocm backplane cloud console -b
  

  Or set the environment variable

  $ export BACKPLANE_DEFAULT_OPEN_BROWSER=true
  $ ocm backplane cloud console
  `
  

Monitoring

Monitoring command can be used to launch the specified monitoring UI.

Run this command from within a cluster :

ocm backplane monitoring <prometheus/alertmanager/thanos/grafana> [flags]

Note: Following version 4.11, Prometheus, AlertManager and Grafana monitoring UIs are deprecated for openshift-monitoring stack, please use 'ocm backplane console' and use the observe tab for the same. Other monitoring stacks remain unaffected.

Backplane Session

Backplane session command will create an isolated environment to interact with a cluster in its own directory. The default location for this is ~/backplane.

The default session save path can be configured via the backplane config file.

{
   "url": "your-bp-url"
   "proxy-url": "your-proxy-url"
   "session-dir":"your-session-dir"
}

How to create new session?

The following command will create a new session and log in to the cluster.

## with intractive session name 
ocm backplane session <session-name> -c <cluster-id>

## only with cluster id
ocm backplane session <cluster-id> 

Backplane session keeps the session history commands in /session-name/.history file.

[ <session-name> (<cluster-info-PS1>)]$ history 
    1  2023-05-08 15:06:05 oc get nodes
    2  2023-05-08 15:06:13 oc get co
    3  2023-05-08 15:06:40 history 

Backplane session setup following environment variables.

HISTFILE    = <your-session-path>/<session-name>/.history
PATH        = <your-os-path>
KUBECONFIG  = <your-session-path>/<session-name>/<cluster-id>/config
CLUSTERID   = <cluster-id>
CLUSTERNAME = <cluster-name>

How to delete the session?

Folowing command delete the session

ocm backplane session --delete <session-name>

Promotion/Release cycle of backplane CLI

Backplane CLI has a default release cycle of every 2 weeks

Debugging issues

To help diagnose any issues, you can modify the default verbosity of the logger. Use -v for info level or explicitly setting the logging level by using --verbosity=debug flag.

For further information on logging levels refer to the in-built help.

$ ocm backplane help
