Publishing your Job as a Docker image
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Follow the steps below to publish a Job as a Docker image.
Before you begin
To publish a Job as an Docker image and execute it on the Google Kubernetes Engine, you need to have:
- A Talend Platform Studio or Talend Data Fabric Studio installed on the client/local machine
- A Docker registry account
- A licensed Google Cloud Platform (GCP) account
Procedure
-
Open Talend Studio and
create a simple standard Job like below, and make sure it runs successfully.
-
Right-click the Job in the Repository tree view, and select
Publish from the contextual menu.
-
From the Export Type, select Docker
Image and click Next.
-
Select Local as the Docker host, and provide the
following details together with your docker registry credentials.
-
Image name: A name for the docker image. A repository
will be created with the same name in the Docker registry.Information noteNote: Due to a restriction on repository names when publishing to registry.hub.docker.com, some characters are not supported in the image name: it must contain a combination of alphanumeric characters and may contain the special characters ., _ or -. Letters must be in lowercase.
- Image tag: A value to tag your Docker image. By default, the Job version will be the tag value.
- Registry: Provide the Docker registry URL with your Docker ID. For Docker Hub, it will be registry.hub.docker.com/dockerId.
- Username and Password: The credentials you use to connect to Docker registry.
-
Image name: A name for the docker image. A repository
will be created with the same name in the Docker registry.
-
Log in to your Docker registry account.
Under the Repositories tab, you can see the Docker image containing the Job was created.
