JSON Output

For odo to be used as a backend by graphical user interfaces (GUIs), the useful commands can output their result in JSON format.

When used with the -o json flags, a command:

that terminates successully, will:
- terminate with a zero exit status,
- will return its result in JSON format in its standard output stream.
that terminates with an error, will:
- terminate with a non-zero exit status,
- will return an error message in its standard error stream, in the unique field message of a JSON object, as in { "message": "file not found" }

The structures used to return information using JSON output are defined in the pkg/api package.

odo analyze -o json

The analyze command analyzes the files in the current directory and returns the following information:

the best devfiles to use, from the devfiles in the registries defined in the list of preferred registries with the command odo preference view
the ports used in the application, if that was possible to determine.
the name of the application, if that was possible to determine; else it returns name of the current directory.

The output of this command contains a list of devfile name and registry name:

odo analyze -o json

[
    {
        "devfile": "nodejs",
        "devfileRegistry": "DefaultDevfileRegistry",
        "ports": [
            3000
        ],
        "name": "node-echo"
    }
]

The exit code should be zero in this case:

$ echo $?
0

If the command is executed in an empty directory, it will return an error in the standard error stream and terminate with a non-zero exit status:

odo analyze -o json

{
    "message": "No valid devfile found for project in /home/user/my/empty/directory"
}

The command should terminate with a non-zero exit code:

$ echo $?
1

odo init -o json

The init command downloads a devfile and, optionally, a starter project. The usage for this command can be found in the odo init command reference page.

The output of this command contains the path of the downloaded devfile and its content, in JSON format.

$ odo init -o json \
    --name aname \
    --devfile go \
    --starter go-starter

{
    "devfilePath": "/home/user/my-project/devfile.yaml",
    "devfileData": {
        "devfile": {
            "schemaVersion": "2.1.0",
      [...]
        },
        "supportedOdoFeatures": {
            "dev": true,
            "deploy": false,
            "debug": false

    },
    "forwardedPorts": [],
    "runningIn": {
        "dev": false,
        "deploy": false
    },
    "managedBy": "odo"
}

echo $?

If the command fails, it will return an error in the standard error stream and terminate with a non-zero exit status:

# Executing the same command again will fail
$ odo init -o json \
    --name aname \
    --devfile go \
    --starter go-starter

{
    "message": "a devfile already exists in the current directory"
}

echo $?

odo describe component -o json

The describe component command returns information about a component, either the component defined by a Devfile in the current directory, or a deployed component given its name and namespace.

When the describe component command is executed without parameter from a directory containing a Devfile, it will return:

information about the Devfile
- the path of the Devfile,
- the content of the Devfile,
- supported odo features, indicating if the Devfile defines necessary information to run odo dev, odo dev --debug and odo deploy
- the list of commands, if any, along with some useful information about each command
- ingress or routes created in Deploy mode
the status of the component
- the forwarded ports if odo is currently running in Dev mode,
- the modes in which the component is deployed (either none, Dev, Deploy or both)

When the describe component commmand is executed with a name and namespace, it will return:

the modes in which the component is deployed (either Dev, Deploy or both)
ingress and route resources created by the component in Deploy mode

The command with name and namespace is not able to return information about a component that has not been deployed.

The command with name and namespace will never return information about the Devfile, even if a Devfile is present in the current directory.

The command with name and namespace will never return information about the forwarded ports, as the information resides in the directory of the Devfile.

odo list -o json

The odo list command returns information about components running on a specific namespace, and defined in the local Devfile, if any.

The components field lists the components either deployed in the cluster, or defined in the local Devfile.

The componentInDevfile field gives the name of the component present in the components list that is defined in the local Devfile, or is empty if no local Devfile is present.

In this example, the component2 component is running in Deploy mode, and the command has been executed from a directory containing a Devfile defining a component1 component, not running.

odo list --namespace project1

{
    "componentInDevfile": "component1",
    "components": [

            },
            "projectType": "nodejs"
        },
        {
            "name": "component1",
            "managedBy": "",
            "runningIn": {
                "dev": false,
                "deploy": false
            },
            "projectType": "nodejs"
        }
    ]
}

odo registry -o json

The odo registry command lists all the Devfile stacks from Devfile registries. You can get the available flag in the registry command reference.

The default output will return information found into the registry index for stacks:

odo registry -o json

odo list binding -o json

The odo list binding command lists all service binding resources deployed in the current namespace, and all service binding resources declared in the Devfile, if executed from a component directory.

The names of the Service Binding resources declared in the current Devfile are listed in the bindingsInDevfile field of the output.

If a Service Binding resource is found in the current namespace, it also displays the variables that can be used from the component in the status.bindingFiles and/or status.bindingEnvVars fields.

Examples

When a service binding resource is defined in the Devfile, and the component is not deployed, you get an output similar to:

odo list binding -o json

{
    "bindingsInDevfile": [
        "my-nodejs-app-cluster-sample"
    ],
    "bindings": [
        {
            "name": "my-nodejs-app-cluster-sample",
            "spec": {
                "application": {
                    "kind": "Deployment",
                    "name": "my-nodejs-app-app",
                    "apiVersion": "apps/v1"
                },
                "services": [
                    {
                        "kind": "Cluster",
                        "name": "cluster-sample",
                        "apiVersion": "postgresql.k8s.enterprisedb.io/v1"
                    }
                ],
                "detectBindingResources": true,
                "bindAsFiles": true
            }
        }
    ]
}

With the same Devfile, when `odo dev` is running, you get an output similar to

                }
            }
        }
    ]
}

When odo dev is running, if you execute the command from a directory without Devfile, you get an output similar to (note that the .bindingsInDevfile field is not present anymore):

odo describe binding -o json

The odo describe binding command lists all the service binding resources declared in the devfile and, if the resource is deployed to the cluster, also displays the variables that can be used from the component.

If a name is given, the command does not extract information from the Devfile, but instead extracts information from the deployed resource with the given name.

Without a name, the output of the command is a list of service binding details, for example:

odo describe binding -o json

odo preference view -o json

The odo preference view command lists all user preferences and all user Devfile registries.

odo preference view -o json

{
    "preferences": [

odo list services -o json

The odo list services command lists all the bindable Operator backed services available in the current project/namespace.

odo list services -o json

$ odo list services -o json
{
    "bindableServices": [
        {
            "name": "cluster-sample",
            "namespace": "myproject",
            "kind": "Cluster",
            "apiVersion": "postgresql.k8s.enterprisedb.io/v1",
            "service": "cluster-sample/Cluster.postgresql.k8s.enterprisedb.io/v1"
        }
    ]
}

You can also list all the bindable Operator backed services from a different project/namespace that you have access to:

odo list services -o json -n <project-name>

$ odo list services -o json -n newproject
{
    "bindableServices": [
        {
            "name": "hello-world",
            "namespace": "newproject",
            "kind": "RabbitmqCluster",
            "apiVersion": "rabbitmq.com/v1",
            "service": "hello-world/RabbitmqCluster.rabbitmq.com/v1"
        }
    ]
}

use -A or --all-namespaces flag:

odo list services -o json -A

$ odo list services -o json -A
{
    "bindableServices": [
        {
            "name": "cluster-sample",
            "namespace": "myproject",
            "kind": "Cluster",
            "apiVersion": "postgresql.k8s.enterprisedb.io/v1",
            "service": "cluster-sample/Cluster.postgresql.k8s.enterprisedb.io/v1"
        },
        {
            "name": "hello-world",
            "namespace": "newproject",
            "kind": "RabbitmqCluster",
            "apiVersion": "rabbitmq.com/v1",
            "service": "hello-world/RabbitmqCluster.rabbitmq.com/v1"
        }
    ]
}

odo list projects -o json

The odo list projects -o json (and odo list namespaces -o json) command lists all the projects on the cluster that you have access to. It marks the currently active namespace as active: true:

odo list projects -o json

$ odo list projects -o json
{
    "namespaces": [
        {
            "name": "proj1",
            "active": false
        },
        {
            "name": "proj2",
            "active": false
        },
        {
            "name": "proj3",
            "active": true
        }
    ]
}

If odo can't find any projects on the cluster that you have access to, it will simply show an empty list:

$ odo list projects -o json
{}

odo version -o json

The odo version -o json returns the version information about odo, cluster server and podman client. Use --client flag to only obtain version information about odo.

odo version -o json [--client]

$ odo version -o json
{
    "version": "v3.11.0",
    "gitCommit": "ea2d256e8",
    "cluster": {
        "serverURL": "https://kubernetes.docker.internal:6443",
        "kubernetes": {
            "version": "v1.25.9"
        },
        "openshift": {
          "version": "4.13.0"
        },
    },
    "podman": {
        "client": {
            "version": "4.5.1"
        }
    }
