Create a managed cluster

Warning

This section only applies to Container Cloud 2.27.2 (Cluster release 16.2.2) or earlier versions. Since Container Cloud 2.27.3 (Cluster release 16.2.3), support for vSphere-based clusters is suspended. For details, see Deprecation notes.

This section describes how to create a VMware vSphere-based managed cluster using the Mirantis Container Cloud web UI of the vSphere-based management cluster.

To create a vSphere-based managed cluster:

  1. Available since Container Cloud 2.24.0. Optional. Technology Preview. Enable custom host names for cluster machines. When enabled, any machine host name in a particular region matches the related Machine object name. For example, instead of the default kaas-node-<UID>, a machine host name will be master-0. The custom naming format is more convenient and easier to operate with.

    For details, see Configure host names for cluster machines.

    If you enabled this feature during management cluster bootstrap, skip this step, as the feature applies to any cluster type.

  2. Log in to the Container Cloud web UI with the m:kaas:namespace@operator or m:kaas:namespace@writer permissions.

  3. Switch to the required non-default project using the Switch Project action icon located on top of the main left-side navigation panel.

    To create a project, refer to Create a project for managed clusters.

  4. Optional. In the SSH Keys tab, click Add SSH Key to upload the public SSH key(s) for VMs creation.

  5. In the Credentials tab:

    1. Click Add Credential to add your vSphere credentials. You can either upload your vSphere vsphere.yaml configuration file or fill in the fields manually.

    2. Verify that the new credentials status is Ready. If the status is Error, hover over the status to determine the reason of the issue.

  6. Optional. Enable proxy access to the cluster.

    In the Proxies tab, configure proxy:

    1. Click Add Proxy.

    2. In the Add New Proxy wizard, fill out the form with the following parameters:

      Proxy configuration

      Parameter

      Description

      Proxy Name

      Name of the proxy server to use during cluster creation.

      Region Removed in 2.26.0 (16.1.0 and 17.1.0)

      From the drop-down list, select the required region.

      HTTP Proxy

      Add the HTTP proxy server domain name in the following format:

      • http://proxy.example.com:port - for anonymous access

      • http://user:password@proxy.example.com:port - for restricted access

      HTTPS Proxy

      Add the HTTPS proxy server domain name in the same format as for HTTP Proxy.

      No Proxy

      Comma-separated list of IP addresses or domain names. Mandatory to add host[:port] of the vCenter server.

      For implementation details, see Proxy and cache support.

    3. If your proxy requires a trusted CA certificate, select the CA Certificate check box and paste a CA certificate for a MITM proxy to the corresponding field or upload a certificate using Upload Certificate.

    For the list of Mirantis resources and IP addresses to be accessible from the Container Cloud clusters, see Requirements for a VMware vSphere-based cluster.

    Since Container Cloud 2.28.0 (Cluster releases 17.3.0 and 16.3.0) in the Technology Preview scope, you can collect some of the preset rules indicated above as groups and use them in presetRules:

    • ubuntu-cis-rules - this group contains rules to comply with the Ubuntu CIS Benchmark recommendations, including the following CIS Ubuntu 20.04 v2.0.1 rules:

      • scope - 5.2.3.1

      • actions - same as 5.2.3.2

      • time-change - 5.2.3.4

      • system-locale - 5.2.3.5

      • privileged - 5.2.3.6

      • access - 5.2.3.7

      • identity - 5.2.3.8

      • perm-mod - 5.2.3.9

      • mounts - 5.2.3.10

      • session - 5.2.3.11

      • logins - 5.2.3.12

      • delete - 5.2.3.13

      • mac-policy - 5.2.3.14

      • modules - 5.2.3.19

    • docker-cis-rules - this group contains rules to comply with Docker CIS Benchmark recommendations, including the docker Docker CIS v1.6.0 rules 1.1.3 - 1.1.18.

    You can also use two additional keywords inside presetRules:

    • none - select no built-in rules.

    • all - select all built-in rules. When using this keyword, you can add the ! prefix to a rule name to exclude some rules. You can use the ! prefix for rules only if you add the all keyword as the first rule. Place a rule with the ! prefix only after the all keyword.

    Example configurations:

    • presetRules: none - disable all preset rules

    • presetRules: docker - enable only the docker rules

    • presetRules: access,actions,logins - enable only the access, actions, and logins rules

    • presetRules: ubuntu-cis-rules - enable all rules from the ubuntu-cis-rules group

    • presetRules: docker-cis-rules,actions - enable all rules from the docker-cis-rules group and the actions rule

    • presetRules: all - enable all preset rules

    • presetRules: all,!immutable,!sessions - enable all preset rules except immutable and sessions
