kubeadm: Create a new bootstrap token with a TTL of 12 hours.
$ kubeadm token create --ttl ${12h0m0s}
try on your machine
The command kubeadm token create --ttl ${12h0m0s}
is used to create a token for authentication in a Kubernetes cluster using the kubeadm
tool.
Here's a breakdown of the command:
kubeadm
: This is the command-line tool for bootstrapping a Kubernetes cluster.token
: This subcommand is used to manage tokens for authentication.create
: This option creates a new token.
The --ttl
flag specifies the time-to-live (TTL) for the token. In this case, it is set to ${12h0m0s}
. The 12h0m0s
represents a duration of 12 hours. You can use different units to define the duration, such as hours (h), minutes (m), or seconds (s). So, ${12h0m0s}
means the token will be valid for 12 hours.
Overall, this command generates a new authentication token for accessing a Kubernetes cluster and sets its validity duration to 12 hours.
