odo list component

odo list component command is useful for getting information about components running on a specific namespace.

If the command is executed from a directory containing a Devfile, it also displays the component defined in the Devfile as part of the list, prefixed with a star(*).

For each component, the command displays:

• its name,
• its project type,
• on which mode it is running (None, Dev, Deploy, or both), note that None is only applicable to the component defined in the local Devfile,
• by which application the component has been deployed.

Running the command

odo list component

Example

$ odo list component
 ✓  Listing components from namespace 'my-percona-server-mongodb-operator' [292ms]
 NAME              PROJECT TYPE  RUNNING IN  MANAGED
 * my-nodejs         nodejs        Deploy      odo (v3.0.0-rc1)
 my-go-app         go            Dev         odo (v3.0.0-rc1)
 mongodb-instance  Unknown       None        percona-server-mongodb-operator 

use of cache

odo list component makes use of cache for performance reasons. This is the same cache that is referred by kubectl command when you do kubectl api-resources --cached=true. As a result, if you were to install an Operator/CRD on the Kubernetes cluster, and create a resource from it using odo, you might not see it in the odo list component output. This would be the case for 10 minutes timeframe for which the cache is considered valid. Beyond this 10 minutes, the cache is updated anyway.

If you would like to invalidate the cache before the 10 minutes timeframe, you could manually delete it by doing:

rm -rf ~/.kube/cache/discovery/api.crc.testing_6443/

Above example shows how to invalidate the cache for a CRC cluster. Note that you will have to modify the api.crc. testing_6443 part based on the cluster you are working against.
