2.10.6. Creating the installation files for AWS
To install OpenShift Container Platform on Amazon Web Services (AWS) using user-provisioned infrastructure, you must generate the files that the installation program needs to deploy your cluster and modify them so that the cluster creates only the machines that it will use. You generate and customize the install-config.yaml
file, Kubernetes manifests, and Ignition config files.
2.10.6.1. Creating the installation configuration file
Generate and customize the installation configuration file that the installation program needs to deploy your cluster.
Prerequisites
- Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your mirror host.
Procedure
Obtain the
install-config.yaml
file.Run the following command:
$ ./openshift-install create install-config --dir=<installation_directory> 1
- 1
- For
<installation_directory>
, specify the directory name to store the files that the installation program creates.
重要Specify an empty directory. Some installation assets, like bootstrap X.509 certificates have short expiration intervals, so you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version.
At the prompts, provide the configuration details for your cloud:
Optional: Select an SSH key to use to access your cluster machines.
注記For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your
ssh-agent
process uses.- Select aws as the platform to target.
- If you do not have an AWS profile stored on your computer, enter the AWS access key ID and secret access key for the user that you configured to run the installation program.
- Select the AWS region to deploy the cluster to.
- Select the base domain for the Route 53 service that you configured for your cluster.
- Enter a descriptive name for your cluster.
- Paste the pull secret that you obtained from the Pull Secret page on the Red Hat OpenShift Cluster Manager site.
Edit the
install-config.yaml
file to set the number of compute replicas, which are also known as worker replicas, to0
, as shown in the followingcompute
stanza:compute: - hyperthreading: Enabled name: worker platform: {} replicas: 0
Edit the
install-config.yaml
file to provide the additional information that is required for an installation in a restricted network.Update the
pullSecret
value to contain the authentication information for your registry:pullSecret: '{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}}'
For
<local_registry>
, specify the registry domain name, and optionally the port, that your mirror registry uses to serve content. For exampleregistry.example.com
orregistry.example.com:5000
. For<credentials>
, specify the base64-encoded user name and password for your mirror registry.Add the
additionalTrustBundle
parameter and value. The value must be the contents of the certificate file that you used for your mirror registry, which can be an exiting, trusted certificate authority or the self-signed certificate that you generated for the mirror registry.additionalTrustBundle: | -----BEGIN CERTIFICATE----- ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ -----END CERTIFICATE-----
Add the image content resources:
imageContentSources: - mirrors: - <local_registry>/<local_repository_name>/release source: quay.io/openshift-release-dev/ocp-release - mirrors: - <local_registry>/<local_repository_name>/release source: quay.io/openshift-release-dev/ocp-v4.0-art-dev
Use the
imageContentSources
section from the output of the command to mirror the repository or the values that you used when you mirrored the content from the media that you brought into your restricted network.Optional: Set the publishing strategy to
Internal
:publish: Internal
By setting this option, you create an internal Ingress Controller and a private load balancer.
Optional: Back up the
install-config.yaml
file.重要The
install-config.yaml
file is consumed during the installation process. If you want to reuse the file, you must back it up now.
