Image Builder

Administrators are able to create custom images with pre-installed tools and libraries which are required for users.

Custom Image List

In Image Builder section, there is a list of created custom image specs with several fields as below:

• Name The name of a custom image spec.

• Status The status of the latest custom built image.

• Image The url of the latest built image once it is built successfully.

• Actions - Edit and Delete.

Create Custom Image Spec

Click + Add button to enter the creation page.

Fill in the fields, some are required:

• Name (required) A unique name, it's not able to be modified once created. (Only lowercase letters, numbers, dash - and the bottom line _ can be filled in.)

• Base image (required) The url of the base image.

• Use Image PullSecret Checked off if a pull secret is required.

• Packages choose packages installer/management and fill in packages requirement.

  • APT Packages management of Debian, Ubuntu and related Linux distribution.

  • Pip Using python packages installer. [Reference]

  • Conda A packages management supports multiple programming language. [Reference]

Note: In case of multiple packages, please using the line break for each package instead of putting them in one line.

Click Confirm to complete the addition.

Once the image is built successfully, the url of the image will be listed.

Edit Custom Image Spec

Click the button to enter the edit page of the custom image spec.

On edit page, there are two tabs, Info and Jobs. Info is exactly same as creation page. We can make modifications to the spec, except the Name which is not editable.

Once any modification is confirmed, a job of image build will be triggered and it will be listed in the tab Jobs.

Jobs

A job is an image build job. Once a creation of a custom image spec is confirmed, the first job of image build is triggered automatically. Afterwards, any confirmed modifications of spec will trigger other image build jobs. Each job logs the spec and the progress.

These jobs/image urls are listed here.

• Updated At The timestamp when the job is updated.

• Image Revision The revision of an custom image.

• Status The status of the custom image creation job.

• Actions - View the spend and logs of an custom image build.

Click the button, we can check the log of each job of image build with its spec.

It is helpful that when we want to know what made image build fail and what spec the image build is based on.

Delete Custom Image Spec

Click the button, the confirmation dialog will pop up, and the custom image spec will be deleted once you click OK.
