odo service

odo can deploy services with the help of operators.

The list of available operators and services available for installation can be found with the odo catalog command.

Services are created in the context of a component, so you should have run odo create before you deploy services.

The deployment of a service is done in two steps:

  1. Define the service and store its definition in the devfile,
  2. Deploy the defined service to the cluster, using odo push.

Creating a new service

You can create a new service with the command:

odo service create

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

$ 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.

$  cat kubernetes/odo-service-my-redis-service.yaml 
apiVersion: redis.redis.opstreelabs.in/v1beta1
kind: Redis
metadata:
name: my-redis-service
spec:
kubernetesConfig:
image: quay.io/opstree/redis:v6.2.5
imagePullPolicy: IfNotPresent
resources:
limits:
cpu: 101m
memory: 128Mi
requests:
cpu: 101m
memory: 128Mi
serviceType: ClusterIP
redisExporter:
enabled: false
image: quay.io/opstree/redis-exporter:1.0
storage:
volumeClaimTemplate:
spec:
accessModes:

resources:
requests:
storage: 1Gi
$ cat devfile.yaml
[...]
components:
- kubernetes:
uri: kubernetes/odo-service-my-redis-service.yaml
name: my-redis-service
[...]

Note that the name of the created instance is optional. If you do not provide a name, it will be the lowercased name of the service. For example, the following command will create an instance of a Redis service named redis:

$ odo service create redis-operator.v0.8.0/Redis

Inlining the manifest

By default, a new manifest is created in the kubernetes/ directory, referenced from the devfile.yaml file. It is possible to inline the manifest inside the devfile.yaml file using the --inlined flag:

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

$ cat devfile.yaml
[...]
components:
- kubernetes:

Configuring the service

Without specific indication, the service will be created with a default configuration. You can use either command-line arguments or a file to specify your own configuration.

Using command-line arguments

You can use the --parameters (or -p) flag to specify your own configuration.

In the following example, we will configure the Redis service with three parameters:

$ odo service create redis-operator.v0.8.0/Redis my-redis-service \
-p kubernetesConfig.image=quay.io/opstree/redis:v6.2.5 \
-p kubernetesConfig.serviceType=ClusterIP \
-p redisExporter.image=quay.io/opstree/redis-exporter:1.0
Successfully added service to the configuration; do 'odo push' to create service on the cluster

$ cat kubernetes/odo-service-my-redis-service.yaml
apiVersion: redis.redis.opstreelabs.in/v1beta1
kind: Redis
metadata:
name: my-redis-service
spec:
kubernetesConfig:
image: quay.io/opstree/redis:v6.2.5
serviceType: ClusterIP
redisExporter:
image: quay.io/opstree/redis-exporter:1.0

You can obtain the possible parameters for a specific service from the odo catalog describe service command.

Using a file

You can use a YAML manifest to specify your own specification.

In the following example, we will configure the Redis service with three parameters. For this, first create a manifest:

$ cat > my-redis.yaml <<EOF
apiVersion: redis.redis.opstreelabs.in/v1beta1
kind: Redis
metadata:
name: my-redis-service
spec:
kubernetesConfig:
image: quay.io/opstree/redis:v6.2.5
serviceType: ClusterIP
redisExporter:
image: quay.io/opstree/redis-exporter:1.0
EOF

Then create the service from the manifest:

$ odo service create --from-file my-redis.yaml
Successfully added service to the configuration; do 'odo push' to create service on the cluster

Deleting a service

You can delete a service with the command:

odo service delete

For example:

$ 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

You can use the --force (or -f) flag to force the deletion of the service without confirmation.

Listing services

You can get the list of services created for your component with the command:

odo service list

For example:

$ 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 odo push, or if the service is still running on the cluster but removed from the devfile locally using odo service delete.

Getting information about a service

You can get the details about a service such as its kind, version, name and list of configured parameters with the command:

odo service describe

For example:

$ 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
