Build & Run Docker Container

  1. Create a Dockerfile on RHEL 8.6 operating system. Internet access is required.

vi Dockerfile

  1. The below Dockerfile is provided as an example for your reference. To make it work on your environment, perform the following:

    1. Use your RHEL 8.6 subscription and license details.

    2. Adjust the highlighted lines below to match the configuration details of your environment.

    3. When building the docker image, make sure OCP_HOST_KERNEL_VER and KERNEL_VER versions are as close as possible. For example, see lines 3-4 highlighted below.

Note

To load the Intel Gaudi driver properly, make sure to use redhat/ubi8:8.6 base image to create the docker image.

  1. Build and run docker container. Make sure the docker image is built on the same operating system where the dockerfile was created.

docker build -f Dockerfile -t hl-core-os:rhel8.6 .

  1. Once build is finished, upload the image to your local docker registry. Example:

docker login <your docker registry URL>
docker push  <your docker registry URL/path (where your docker is stored) images/hl-core-os:rhel8.6>

Note

Make sure your OCP host has access to above docker registry.

  1. Run docker container with the below command:

sudo podman run --name hl-rhel-coreos --entrypoint=bash --privileged=true -it  <your docker registry URL/path_where_your_docker_image_stored/hl-core-os:rhel8.6>

After running the above command, the docker prompt CLI will open. You are now inside the running docker container.
