To create a devfile for an existing project, run the odo create command with the name and type of your component (for example, nodejs or go):

odo create nodejs mynodejs

In the example, nodejs is the type of the component and mynodejs is the name of the component that odo creates for you.

If your source code exists outside the current directory, the --context flag can be used to specify the path. For example, if the source for the nodejs component is in a folder called node-backend relative to the current working directory, run the command:

odo create nodejs mynodejs --context ./node-backend

The --context flag supports relative and absolute paths.

To specify the project or app where your component will be deployed, use the --project and --app flags. For example, to create a component that is part of the myapp app inside the backend project, run the command:

odo create nodejs --app myapp --project backend

Use the starter projects if you do not have existing source code but want to get up and running quickly to experiment with devfiles and components. To use a starter project, add the --starter flag to the odo create command.

To get a list of available starter projects for a component type, run the odo catalog describe component command. For example, to get all available starter projects for the nodejs component type, run the command:

odo catalog describe component nodejs

Then specify the desired project using the --starter flag on the odo create command:

odo create nodejs --starter nodejs-starter

This will download the example template corresponding to the chosen component type, in this instance, nodejs. The template is downloaded to your current directory, or to the location specified by the --context flag. If a starter project has its own devfile, then this devfile will be preserved.

If you want to create a new component from an existing devfile, you can do so by specifying the path to the devfile using the --devfile flag. For example, to create a component called mynodejs, based on a devfile from GitHub, use the following command:

odo create mynodejs --devfile https://raw.githubusercontent.com/odo-devfiles/registry/master/devfiles/nodejs/devfile.yaml

You can also run the odo create command interactively, to guide you through the steps needed to create a component:

$ odo create

? Which devfile component type do you wish to create go
? What do you wish to name the new devfile component go-api
? What project do you want the devfile component to be created in default
Devfile Object Validation
 ✓  Checking devfile existence [164258ns]
 ✓  Creating a devfile component from registry: DefaultDevfileRegistry [246051ns]
Validation
 ✓  Validating if devfile name is correct [92255ns]
? Do you want to download a starter project Yes

Starter Project
 ✓  Downloading starter project go-starter from https://github.com/devfile-samples/devfile-stack-go.git [429ms]

Please use odo push command to create the component with source deployed

You are prompted to choose the component type, name, and the project for the component. You can also choose whether or not to download a starter project. Once finished, a new devfile.yaml file is created in the working directory.

To deploy these resources to your cluster, run the command odo push.

To delete a devfile component, run the odo delete command:

$ odo delete

If the component has been pushed to the cluster, the component is deleted from the cluster, along with its dependent storage, URL, secrets, and other resources. If the component has not been pushed, the command exits with an error stating that it could not find the resources on the cluster.

Use the -f or --force flag to avoid the confirmation questions.

To undeploy the devfile Kubernetes components, that have been deployed with odo deploy, execute the odo delete command with the --deploy flag:

$ odo delete --deploy

Use the -f or --force flag to avoid the confirmation questions.

To delete all artifacts including the following items, run the odo delete command with the --all flag :

$ odo delete --all

The documentation on Common Flags provides more information on the flags available for commands.

odo provides various options for linking a component with an Operator-backed service or another odo component. All these options (or flags) can be used whether you are linking a component to a service or to another component.

Another helpful flag that odo link provides is --bind-as-files. When this flag is passed, the binding information is not injected into the component’s Pod as environment variables but is mounted as a filesystem.

Ensure that there are no existing links between the backend component and the PostgreSQL service. You could do this by running odo describe in the backend component’s directory and check if you see output similar to the following:

Linked Services:
 · PostgresCluster/hippo

Unlink the service from the component using:

$ odo unlink PostgresCluster/hippo
$ odo push

To list the registries currently contacted by odo, run the command:

$ odo registry list

NAME                       URL                             SECURE
DefaultDevfileRegistry     https://registry.devfile.io     No

DefaultDevfileRegistry is the default registry used by odo; it is provided by the devfile.io project.

To add a registry, run the command:

$ odo registry add

$ odo registry add StageRegistry https://registry.stage.devfile.io
New registry successfully added

If you are deploying your own Secure Registry, you can specify the personal access token to authenticate to the secure registry with the --token flag:

$ odo registry add MyRegistry https://myregistry.example.com --token <access_token>
New registry successfully added

To delete a registry, run the command:

$ odo registry delete

$ odo registry delete StageRegistry
? Are you sure you want to delete registry "StageRegistry" Yes
Successfully deleted registry

Use the --force (or -f) flag to force the deletion of the registry without confirmation.

To update the URL or the personal access token of a registry already registered, run the command:

$ odo registry update

 $ odo registry update MyRegistry https://otherregistry.example.com --token <other_access_token>
 ? Are you sure you want to update registry "MyRegistry" Yes
 Successfully updated registry

Use the --force (or -f) flag to force the update of the registry without confirmation.

To create a new service, run the command:

$ odo service create

For example, to create an instance of a Redis service named my-redis-service, you can run the following command:

$ odo catalog list services
Services available through Operators
NAME                      CRDs
redis-operator.v0.8.0     RedisCluster, Redis

$ odo service create redis-operator.v0.8.0/Redis my-redis-service
Successfully added service to the configuration; do 'odo push' to create service on the cluster

This command creates a Kubernetes manifest in the kubernetes/ directory, containing the definition of the service, and this file is referenced from the devfile.yaml file.

To delete a service, run the command:

$ odo service delete

$ odo service list
NAME                       MANAGED BY ODO     STATE               AGE
Redis/my-redis-service     Yes (api)          Deleted locally     5m39s

$ odo service delete Redis/my-redis-service
? Are you sure you want to delete Redis/my-redis-service Yes
Service "Redis/my-redis-service" has been successfully deleted; do 'odo push' to delete service from the cluster

Use the --force (or -f) flag to force the deletion of the service without confirmation.

To list the services created for your component, run the command:

$ odo service list

$ odo service list
NAME                       MANAGED BY ODO     STATE             AGE
Redis/my-redis-service-1   Yes (api)          Not pushed
Redis/my-redis-service-2   Yes (api)          Pushed            52s
Redis/my-redis-service-3   Yes (api)          Deleted locally   1m22s

For each service, STATE indicates if the service has been pushed to the cluster using the odo push command, or if the service is still running on the cluster but removed from the devfile locally using the odo service delete command.

To get details of a service such as its kind, version, name, and list of configured parameters, run the command:

$ odo service describe

$ odo service describe Redis/my-redis-service
Version: redis.redis.opstreelabs.in/v1beta1
Kind: Redis
Name: my-redis-service
Parameters:
NAME                           VALUE
kubernetesConfig.image         quay.io/opstree/redis:v6.2.5
kubernetesConfig.serviceType   ClusterIP
redisExporter.image            quay.io/opstree/redis-exporter:1.0

To add a storage volume to the cluster, run the command:

$ odo storage create

$ odo storage create store --path /data --size 1Gi
✓  Added storage store to nodejs-project-ufyy

$ odo storage create tempdir --path /tmp --size 2Gi --ephemeral
✓  Added storage tempdir to nodejs-project-ufyy

Please use `odo push` command to make the storage accessible to the component

In the above example, the first storage volume has been mounted to the /data path and has a size of 1Gi, and the second volume has been mounted to /tmp and is ephemeral.

To check the storage volumes currently used by the component, run the command:

$ odo storage list

$ odo storage list
The component 'nodejs-project-ufyy' has the following storage attached:
NAME      SIZE     PATH      STATE
store     1Gi      /data     Not Pushed
tempdir   2Gi      /tmp      Not Pushed

To delete a storage volume, run the command:

$ odo storage delete

$ odo storage delete store -f
Deleted storage store from nodejs-project-ufyy

Please use `odo push` command to delete the storage from the cluster

In the above example, using the -f flag force deletes the storage without asking user permission.

If your devfile has multiple containers, you can specify which container you want the storage to attach to, using the --container flag in the odo storage create command.

The following example is an excerpt from a devfile with multiple containers :

components:
  - name: nodejs1
    container:
      image: registry.access.redhat.com/ubi8/nodejs-12:1-36
      memoryLimit: 1024Mi
      endpoints:
        - name: "3000-tcp"
          targetPort: 3000
      mountSources: true
  - name: nodejs2
    container:
      image: registry.access.redhat.com/ubi8/nodejs-12:1-36
      memoryLimit: 1024Mi

In the example, there are two containers,nodejs1 and nodejs2. To attach storage to the nodejs2 container, use the following command:

$ odo storage create --container

$ odo storage create store --path /data --size 1Gi --container nodejs2
✓  Added storage store to nodejs-testing-xnfg

Please use `odo push` command to make the storage accessible to the component

You can list the storage resources, using the odo storage list command:

$ odo storage list

The component 'nodejs-testing-xnfg' has the following storage attached:
NAME      SIZE     PATH      CONTAINER     STATE
store     1Gi      /data     nodejs2       Not Pushed
