What
Replaces the removed
talosctl gencommands on the v1.15 Certificate Management page.Why
Talos 1.15 removes
talosctl gen ca,gen crt,gen csr,gen key, andgen keypair. The "From control plane machine configuration" section usedgen key,gen csr, andgen crtto create a client certificate, so its steps fail on Talos 1.15.Change
talosconfigwith commands that exist in 1.15:talosctl gen secrets --from-controlplane-config controlplane.yaml -o secrets.yamlextracts a secrets bundle, including the Talos API CA.talosctl gen config --with-secrets secrets.yaml --output-types talosconfiggenerates thetalosconfig, as in "From secrets bundle", which the section links to.talosctl --talosconfig talosconfig config endpointsets the endpoints, which the generated file doesn't have.yqandbase64CA extraction and the hand-editedtalosconfigYAML.Testing
talosctl. Starting from onlycontrolplane.yaml, followed the three steps as written. The regeneratedtalosconfigauthenticated against the node:talosctl versionandtalosctl get machineconfig(which needsos:admin) both succeeded. Before theconfig endpointstep it failed withfailed to determine endpoints. The new client certificate has theos:adminrole, is valid for one year, and is issued by the cluster's Talos API CA.talosctlcontainer image, and on one Talos v1.15.0-beta.0 EC2 instance (deleted after the test).
