Finalize the bootstrap¶
Run the bootstrap script:
When the bootstrap is complete, collect and save the following management cluster details in a secure location:
kubeconfigfile located in the same directory as the bootstrap script. This file contains the admin credentials for the management cluster.
ssh_keyfor access to the management cluster nodes that is located in the same directory as the bootstrap script.
If the initial version of your Container Cloud management cluster was earlier than 2.6.0,
openstack_tmpand is located at
The URL for the Container Cloud web UI.
To create users with permissions required for accessing the Container Cloud web UI, see Create initial users after a management cluster bootstrap.
The StackLight endpoints. For details, see Access StackLight web UIs.
The Keycloak URL that the system outputs when the bootstrap completes. The admin password for Keycloak is located in
kaas-bootstrap/passwords.ymlalong with other IAM passwords.
The Container Cloud web UI and StackLight endpoints are available through Transport Layer Security (TLS) and communicate with Keycloak to authenticate users. Keycloak is exposed using HTTPS and self-signed TLS certificates that are not trusted by web browsers.
To use your own TLS certificates for Keycloak, refer to Configure TLS certificates for cluster applications.
When the bootstrap is complete, the bootstrap cluster resources are freed up.
Verify that network addresses used on your clusters do not overlap with the following default MKE network addresses for Swarm and MCR:
10.0.0.0/16is used for Swarm networks. IP addresses from this network are virtual.
10.99.0.0/16is used for MCR networks. IP addresses from this network are allocated on hosts.
Verification of Swarm and MCR network addresses
To verify Swarm and MCR network addresses, run on any master node:
Example of system response:
Server: ... Swarm: ... Default Address Pool: 10.0.0.0/16 SubnetSize: 24 ... Default Address Pools: Base: 10.99.0.0/16, Size: 20 ...
Not all of Swarm and MCR addresses are usually in use. One Swarm Ingress network is created by default and occupies the
10.0.0.0/24address block. Also, three MCR networks are created by default and occupy three address blocks:
To verify the actual networks state and addresses in use, run:
docker network ls docker network inspect <networkName>
