Build containers from terminal

This section shows how to build containers manually from dockerfiles present in your Intel® Developer Cloud for the Edge filesystem inside the JupyterLab interface. Containers built in your JupyterLab terminal session can then be pushed to your private registry associated with your Intel® Developer Cloud for the Edge Container Playground account to test on various Intel Platforms.
See Import Code and Build Containers to import source code already hosted in a git repository with just a few clicks using the web user interface.

Navigate to CLI

Use the top navigation menu to access the
Coding Environment
 to open the JupyterLab interface in a new browser tab. Use the
+
 button from the JupyterLab file browser to open a
Terminal
 from the Launcher.
If you not able to access the JupyterLab interface, make sure to
Allow Pop-ups
 in your browser.

Build a Container

Use the JupyterLab terminal to build the container with
buildah
:
buildah bud --format docker -f DOCKERFILE_NAME.Dockerfile -t CONTAINER_NAME:CONTAINER_TAG .
The list of containers built from the JupyterLab interface can be viewed with the
buildah images
 command. You can also run
buildah bud --format docker -t CONTAINER_NAME:CONTAINER_TAG .
 inside the directory containing the file
.Dockerfile
.
You cannot run the built container inside the Jupyterlab interface. See the next section to first push the container to your Intel® Developer Cloud for the Edge private container registry as a resource and Test Containers.

Push to Private Registry

You must retag your container to begin with the private registry URL associated with your Intel® Developer Cloud for the Edge account. Use the environment variable
$REGISTRY_URL
 to rename your container.
buildah tag CONTAINER_NAME:CONTAINER_TAG $REGISTRY_URL/CONTAINER_NAME:CONTAINER_TAG
To run and test the containers built in the JupyterLab interface inside a project in the container playground portal push your retagged container with the below command.
buildah push $REGISTRY_URL/CONTAINER_NAME:CONTAINER_TAG

Customize a Sample Application

Your Intel® Developer Cloud for the Edge storage filesystem includes the latest source code for the sample applications hosted on Intel® Developer Cloud for the Edge Marketplace. Each sample includes detailed instructions on:
  • How it Works?
  • Supported Runtime Configurations
  • Build and Run commands on Intel® Developer Cloud for the Edge Container Playground and your local system
The
View/Edit Code
 option from the Marketplace opens up the readme for each sample in the JupyterLab environment. You can also visit the public repository:
Try building a simple container with below example:
  • Create and navigate inside a working directory:
    mkdir cli-example && cd cli-example
  • Write a dockerfile for a lightweight container that prints numbers:
    (echo FROM python:slim && echo 'ENTRYPOINT [ "seq", "30"]') > Dockerfile
  • Build the container while including private registry url:
    buildah bud --format docker -t $REGISTRY_URL/cli-example:latest
  • Push the container to assign a project and launch:
    buildah push $REGISTRY_URL/cli-example:latest
