Add or update a CA certificate for a MITM proxy using API¶
Note
For MOSK, the feature support will become available in one of the following Container Cloud releases.
When you enable a man-in-the-middle (MITM) proxy access to a managed cluster,
your proxy requires a trusted CA certificate. This section describes how to
manually add the caCertificate
field to the spec
section
of the Proxy
object. You can also use this instruction to update an
expired certificate on an existing cluster.
To add or update a CA certificate for a MITM proxy using API:
Encode your proxy CA certificate. For example:
cat ~/.mitmproxy/mitmproxy-ca-cert.cer | base64 -w0
Replace
~/.mitmproxy/mitmproxy-ca-cert.cer
with the path to your CA certificate file.Open the existing
Proxy
object for editing:kubectl --kubeconfig <pathToManagementClusterKubeconfig> -n <projectName> edit proxy <proxyName>
In the system response, find the
spec
section with the current proxy configuration. For example:spec: httpProxy: http://172.19.123.57:8080 httpsProxy: http://172.19.123.57:8080
In the
spec
section, add or update thespec.caCertificate
field with the base64-encoded proxy CA certificate data. For example:spec: caCertificate: <BASE64_ENCODED_CA_CERTIFICATE> httpProxy: http://172.19.123.57:8080 httpsProxy: http://172.19.123.57:8080
Save the
Proxy
object and proceed with the managed cluster creation. If you update an expired certificate on an existing managed cluster, wait until the machines switch from theReconfigure
toReady
state to apply changes.
