zwe migrate for kubernetes [parameter [parameter]...]

Description

Migrate your YAML configuration on z/OS for Kubernetes.

This script will create zowe-config ConfigMap and zowe-certificates-secret Secret for Kubernetes deployment.

To manually create zowe-config ConfigMap, the data section should contain a key zowe.yaml with string value of your zowe.yaml used on z/OS.

To manually create zowe-certificates-secret Secret, you need 2 entries under data section:

• keystore.p12: which is base64 encoded PKCS#12 keystore,
• truststore.p12: which is base64 encoded PKCS#12 truststore.

And 3 entries under stringData section:

• keystore.key: is the PEM format of certificate private key,
• keystore.cer: is the PEM format of the certificate,
• ca.cer: is the PEM format of the certificate authority.

In order to make certificates working in Kubernetes, the certificate you are using should have these domains defined in certificate Subject Alt Name (SAN):

• your external domains to access Zowe APIML Gateway Service running in Kubernetes cluster,
• *.<k8s-namespace>.svc.<k8s-cluster-name>
• *.discovery-service.<k8s-namespace>.svc.<k8s-cluster-name>
• *.gateway-service.<k8s-namespace>.svc.<k8s-cluster-name>
• *.<k8s-namespace>.pod.<k8s-cluster-name>

<k8s-namespace> is the Kubernetes Namespace you installed Zowe into. And <k8s-cluster-name> is the Kubernetes cluster name, which usually should be cluster.local.

Without the additional domains in SAN, you may see warnings/errors related to certificate validation.

If you cannot add those domains into certificate Subject Alt Name (SAN), you can change zowe.verifyCertificates to NONSTRICT mode. Zowe components will not validate domain names but will continue to validate certificate chain, validity and whether it's trusted in Zowe truststore.

IMPORTANT: It's not recommended to disable zowe.verifyCertificates.

NOTES: With below conditions, this migration script will re-generate a new set of certificate for you with proper domain names listed above.

• you use zwe init command to initialize Zowe,
• use PKCS#12 format keystore by defining zowe.setup.certificate.type: PKCS12
• did not define zowe.setup.certificate.pkcs12.import.keystore and let zwe command to generate PKCS12 keystore for you
• enabled STRICT mode zowe.verifyCertificates.
