Migrating to Okteto CLI 2.0

The launch of Okteto CLI 2.0 provides support for Okteto Manifest v2.

The Okteto CLI 2.0 was introduced in Okteto 0.11.0. Older versions of Okteto are not able to support version 2.0 of the CLI.

The goal of the new manifest format is to have a single for defining the build, deployment, and development of your application. The v2 manifest also consolidates the various actions possible with previous versions into one command, the improved okteto up command. Previously, developers would have to run a series of commands, such as okteto pipeline deploy or okteto stack deploy and then okteto up. The choice between using either the pipeline or stack commands was often a tripping point for our users and introduced needless complexity. After a user figured this out, they were still not in setup to start active development. The user still needed to run the okteto up command. With v2, a single run of okteto up will build images, deploy your application, and activate your development container. Note that there are still commands for all the intermediary operations to use when desired:

  • okteto build: builds the images defined in the okteto manifest.
  • okteto deploy: deploys your dev environment.
  • okteto deploy --build: forces a build of the defined images before deploying the dev environment.
  • okteto up: activates your dev container.
  • okteto up --deploy: forces a redeploy of your development environment before activating your dev container.

To facilitate the migration of a v1 okteto manifest to v2 we will cover the following scenarios:

  • Scenario 1 Developers with a docker-compose and a v1 manifest
  • Scenario 2 Developers with an okteto pipeline file and a v1 manifest
  • Scenario 3 Developers with a compose file, pipeline file and a v1 manifest

Scenario 1: Compose and v1 Manifest

This scenario provides an example of transitioning to a v2 manifest using a compose file and a v1 dev manifest. You will continue to use your compose file, providing slight modifications by indexing the services and adding a deploy section.

v1 manifest

okteto.yml

name: frontend
image: okteto/node:16
command: bash
sync:
- .:/app

v2 manifest

okteto.yml

deploy:
compose: docker-compose.yml
dev:
frontend:
image: okteto/node:16
command: bash
sync:
- .:/app

Scenario 2: Pipeline and Multiple v1 Manifests

The following scenario demonstrates converting from an okteto pipeline and v1 manifest to a single v2 manifest. The example files are for a project that uses a pipeline to deploy a 3rd party PostgreSQL helm chart, build your app, and then deploy with a local helm chart.

The conversion is peformed as follows:

  • Move the deploy section of the pipeline into a new okteto.yml v2 manifest.
  • Take any okteto build commands from that deploy section and create a new and separate build section in the v2 manifest.
  • Add all the v1 manifest instructions into indexed sections of the dev portion of the v2 manifest.

The files used with okteto v1 are:

  • okteto-pipeline.yml -> The pipeline manifest.
  • frontend/okteto.yml -> The v1 okteto manifest for the frontend service.
  • api/okteto.yml -> The v1 okteto manifest for the api service.

The migration to v2 would result in a single okteto.yml at the root of your project. The example files are as follows:

v1 manifests

okteto-pipeline.yml

deploy:
- helm repo add bitnami https://charts.bitnami.com/bitnami
- helm upgrade --install postgresql bitnami/postgresql
- okteto build -t okteto.dev/frontend:${OKTETO_GIT_COMMIT} frontend
- okteto build -t okteto.dev/api:${OKTETO_GIT_COMMIT} api
- helm upgrade --install frontend frontend/chart --set image=okteto.dev/frontend:${OKTETO_GIT_COMMIT}
- helm upgrade --install api api/chart --set image=okteto.dev/api:${OKTETO_GIT_COMMIT}

frontend/okteto.yml

name: frontend
image: okteto/node:16
command: bash
sync:
- .:/app

api/okteto.yml

name: api
image: okteto/golang:1
command: bash
sync:
- .:/app

v2 manifest

The following variables are available within your v2 manifest to refer to the latest build of the images defined in the build section.

  • ${OKTETO_BUILD_<service>_TAG}: SHA for the last image build at the registry
  • ${OKTETO_BUILD_<service>_REGISTRY}: the registry URL where the image was pushed
  • ${OKTETO_BUILD_<service>_REPOSITORY}: the name of the image that was pushed (namespace/<service>)
  • ${OKTETO_BUILD_<service>_IMAGE}: the full image reference (using its SHA)

okteto.yml

build:
frontend:
context: frontend
api:
context: api

deploy:
- helm repo add bitnami https://charts.bitnami.com/bitnami
- helm upgrade --install postgresql bitnami/postgresql
- helm upgrade --install frontend frontend/chart --set image=${OKTETO_BUILD_FRONTEND_IMAGE}
- helm upgrade --install api api/chart --set image=${OKTETO_BUILD_API_IMAGE}

dev:
frontend:
image: okteto/node:16
command: bash
sync:
- frontend:/app
api:
image: okteto/golang:1
command: bash
sync:
- api:/app

Scenario 3: Pipeline, Compose and Multiple v1 Manifests

Scenario 3 is similar to Scenario 2, except we are no longer using a 3rd party helm chart to deploy PostgreSQL. Now we are using a separate docker compose file called db-compose.yml.

v1 manifests

We start with a similar v1 manifest and pipeline as in scenario 2 except the pipeline is using the deprecated okteto stack command to deploy db-compose.yml

okteto-pipeline.yml

deploy:
- okteto stack deploy -f db-compose.yml
- okteto build -t okteto.dev/frontend:${OKTETO_GIT_COMMIT} frontend
- okteto build -t okteto.dev/api:${OKTETO_GIT_COMMIT} api
- helm upgrade --install frontend frontend/chart --set image=okteto.dev/frontend:${OKTETO_GIT_COMMIT}
- helm upgrade --install api api/chart --set image=okteto.dev/api:${OKTETO_GIT_COMMIT}

frontend/okteto.yml

name: frontend
image: okteto/node:16
command: bash
sync:
- .:/app

api/okteto.yml

name: api
image: okteto/golang:1
command: bash
sync:
- .:/app

v2 manifest

The resulting v2 okteto manifest is again similar to that of scenario 2. However, we have used extended notation in the deploy section to launch our PostgreSQL dependency from db-compose.yml.

The following variables are available within your v2 manifest in order to refer to the latest build of the images defined in the build section.

  • ${OKTETO_BUILD_<service>_TAG}: SHA for the last image build at the registry
  • ${OKTETO_BUILD_<service>_REGISTRY}: the registry URL where the image was pushed
  • ${OKTETO_BUILD_<service>_REPOSITORY}: the name of the image that was pushed (namespace/<service>)
  • ${OKTETO_BUILD_<service>_IMAGE}: the full image reference (using its SHA)

okteto.yml

build:
frontend:
context: frontend
api:
context: api

deploy:
compose: db-compose.yml
commands:
- helm upgrade --install frontend frontend/chart --set image=${OKTETO_BUILD_FRONTEND_IMAGE}
- helm upgrade --install api api/chart --set image=${OKTETO_BUILD_API_IMAGE}

dev:
frontend:
image: okteto/node:16
command: bash
sync:
- frontend:/app
api:
image: okteto/golang:1
command: bash
sync:
- api:/app

Happy coding!
