1. Create a new kubeconfig file **after** cluster creation
|
||||
- `#!bash k3d kubeconfig get mycluster`
|
||||
- *Note:* this will create (or update) the file `$HOME/.k3d/kubeconfig-mycluster.yaml`
|
||||
- *Tip:* Use it: `#!bash export KUBECONFIG=$(k3d kubeconfig get mycluster)`
|
||||
2. Update your default kubeconfig **upon** cluster creation
|
||||
- `#!bash k3d cluster create mycluster --update-kubeconfig`
|
||||
- *Note:* this won't switch the current-context (append `--switch-context` to do so)
|
||||
3. Update your default kubeconfig **after** cluster creation
|
||||
- `#!bash k3d kubeconfig merge mycluster --merge-default-kubeconfig`
|
||||
- *Note:* this won't switch the current-context (append `--switch-context` to do so)
|
||||
4. Update a different kubeconfig **after** cluster creation
|
||||
- `#!bash k3d get kubeconfig mycluster --output some/other/file.yaml`

None of the above options switch the current-context by default.

This is intended to be least intrusive, since the current-context has a global effect.

You can switch the current-context directly with the `kubeconfig merge` command by adding the `--switch` flag.

## Removing cluster details from the kubeconfig
|
||||
|
||||
`#!bash k3d delete cluster mycluster` will always remove the details for `mycluster` from the default kubeconfig.
|

It will also delete the respective kubeconfig file in `$HOME/.k3d/` if it exists.

## Handling multiple clusters
|
||||
|
||||
`k3d get kubeconfig` let's you specify one or more clusters via arguments _or_ all via `--all`.
|
||||
All kubeconfigs will then be merged into a single file if `--merge-default-kubeconfig` or `--output` is specified.
|
||||
If none of those two flags was specified, a new file will be created per cluster and the merged path (e.g. `$HOME/.k3d/kubeconfig-cluster1.yaml:$HOME/.k3d/cluster2.yaml`) will be returned.
|
||||
Note, that with multiple cluster specified, the `--switch-context` flag will change the current context to the cluster which was last in the list.
