Create an image root from an IMS recipe.
cray-ims, the Image Management Service (IMS)cray-nexus, the Nexus repository manager servicekubectl is installed locally and configured to point at the SMS Kubernetes cluster.The commands in this procedure must be run as the root user.
Check for an existing IMS public key ID.
Skip this step if it is known that a public key associated with the user account being used was not previously uploaded to the IMS service.
The following query may return multiple public key records. The correct one will have a name value including the current username in use.
cray ims public-keys list
Example output excerpt:
[[results]]
public_key = "ssh-rsa AAAAB3NzaC1yc2EA ... AsVruw1Zeiec2IWt"
id = "a252ff6f-c087-4093-a305-122b41824a3e"
name = "username public key"
created = "2018-11-21T17:19:07.830000+00:00"
If a public key associated with the username in use is not returned, proceed to the next step. If a public key associated with the username does exist, create a variable for
the IMS public key id value in the returned data and then proceed to step 3.
IMS_PUBLIC_KEY_ID=a252ff6f-c087-4093-a305-122b41824a3e
Upload the SSH public key to the IMS service.
Skip this step if an IMS public key record has already been created for the account being used.
The IMS debug/configuration shell relies on passwordless SSH. This SSH public key needs to be uploaded to IMS to enable interaction with the image customization environment later in this procedure.
Replace the username value with the actual username being used on the system when setting the public key name.
cray ims public-keys create --name "username public key" --public-key ~/.ssh/id_rsa.pub
Example output:
public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCl50gK4l9uupxC2KHxMpTNxPTJbnwEdWy1jst5W5LqJx9fdTrc9uNJ33HAq+WIOhPVGbLm2N4GX1WTUQ4+wVOSmmBBJnlu/l5rmO9lEGT6U8lKG8dA9c7qhguGHy7M7WBgdW/gWA16gwE/u8Qc2fycFERRKmFucL/Er9wA0/Qvz7/U59yO+HOtk5hvEz/AUkvaaoY0IVBfdNBCl59CIdZHxDzgXlXzd9PAlrXZNO8jDD3jyFAOvMMRG7py78zj2NUngvsWYoBcV3FcREZJU529uJ0Au8Vn9DRADyB4QQS2o+fa6hG9i2SzfY8L6vAVvSE7A2ILAsVruw1Zeiec2IWt"

created = "2018-11-21T17:19:07.830000+00:00"
If successful, create a variable for the IMS public key id value in the returned data.

IMS_RECIPE_ID=2233c82a-5081-4f67-bec4-4b59a60017a6
Create an IMS job record and start the image creation job.
After building an image, IMS will automatically upload any build artifacts (root file system, kernel and initrd) to the artifact repository, and associate them with IMS.
IMS is not able to dynamically determine the Linux kernel and initrd to look for because the file name for these vary depending upon Linux distribution, Linux version,
dracut configuration, and more. Thus, the user must pass the name of the kernel and initrd that IMS will look for in the resultant image root’s /boot directory.
Use the following table to help determine the default kernel and initrd file names to specify when submitting the job to customize an image. These are just default names.
Please consult with the site administrator to determine if these names have been changed for a given image or recipe.
| Recipe | Recipe Name | Kernel File Name | initrd File Name |

The wait-for-repos container will ensure that any HTTP/HTTPS repositories referenced by the Kiwi-NG recipe can be accessed and are available. This helps ensure that the
image will be built successfully. If 301 responses are returned instead of 200 responses, that does not indicate an error.

IMPORTANT: The IMS image creation workflow automatically copies the NCN Certificate Authority’s public certificate to
/etc/cray/ca/certificate_authority.crtwithin the image root being built. This can be used to enable secure communications between the NCN and the client node.
If the image creation operation fails, the build artifacts will not be uploaded to S3. If enable_debug is set to true, then the IMS creation job will enable a debug SSH
shell that is accessible by one or more dynamic host names. The user needs to know if they will SSH from inside or outside the Kubernetes cluster to determine which host name
to use. Typically, customers access the system from outside the Kubernetes cluster using the Customer Access Network (CAN).
If no errors are observed, skip to the 1. Verify that the new image was created correctly step.
Otherwise, proceed to the following step to debug the failure.
Use the IMS_JOB_ID to look up the ID of the newly created image.
There may be multiple records returned. Ensure that the correct record is selected in the returned data.

IMPORTANT: The following command will not work when run on a node within the Kubernetes cluster.
ssh -p IMS_SSH_PORT root@IMS_SSH_HOST
Example output:
Last login: Tue Sep 4 18:06:27 2018 from gateway
[root@POD ~]#
Investigate using the IMS debug shell.
Change to the /mnt/image/ directory.
[root@POD image]# cd /mnt/image/
Access the image root.
[root@POD image]# chroot image-root/
Investigate inside the image debug shell.
Exit the image root.
:/ # exit
[root@POD image]#
Touch the complete file once investigations are complete.
[root@POD image]# touch /mount/image/complete
Verify that the new image was created correctly.

Delete the IMS job record.
cray ims jobs delete $IMS_JOB_ID
Deleting the job record will delete the underlying Kubernetes job, service, and ConfigMap that were created when the job record was submitted.
Images built by IMS contain only the packages and settings that are referenced in the Kiwi-NG recipe used to build the image. The only exception is that IMS will dynamically install the system’s root CA certificate to allow Zypper (via Kiwi-NG) to talk securely with the required Nexus RPM repositories. Images that are intended to be used to boot a CN or other node must be configured with DNS and other settings that enable the image to talk to vital services. A base level of customization is provided by the default Ansible plays used by the Configuration Framework Service (CFS) to enable DNS resolution; these plays are typically run against an image after it is built by IMS.
When customizing an image via Customize an Image Root Using IMS, once in the image root using chroot (or if using a `jailed`
environment), the image will only have access to whatever configuration the image already contains. In order to talk to services, including Nexus RPM repositories, the image
root must first be configured with DNS and other settings. That base level of customization is provided by the default Ansible plays used by CFS to enable DNS resolution.
