= up

The `operator-sdk up` command has subcommands that can launch the Operator in
various ways.

== local

The `local` subcommand launches the Operator on the local machine by building
the Operator binary with the ability to access a Kubernetes cluster using a
`kubeconfig` file.

.`up local` arguments
[options="header",cols="1,3"]
|===
|Arguments |Description

|`--kubeconfig` (string)
|The file path to a Kubernetes configuration file. Defaults: `$HOME/.kube/config`

|`--namespace` (string)
|The namespace where the Operator watches for changes. Default: `default`

|`--operator-flags`
|Flags that the local Operator may need. Example: `--flag1 value1 --flag2=value2`

|`-h, --help`
|Usage help output.

.Example output
----
$ operator-sdk up local \
  --kubeconfig "mycluster.kubecfg" \
  --namespace "default" \
  --operator-flags "--flag1 value1 --flag2=value2"
----

The following example uses the default `kubeconfig`, the default namespace
environment variable, and passes in flags for the Operator. To use the Operator
flags, your Operator must know how to handle the option. For example, for an
Operator that understands the `resync-interval` flag:

----
$ operator-sdk up local --operator-flags "--resync-interval 10"
----

If you are planning on using a different namespace than the default, use the
`--namespace` flag to change where the Operator is watching for Custom Resources (CRs)
to be created:

----
$ operator-sdk up local --namespace "testing"
----

For this to work, your Operator must handle the `WATCH_NAMESPACE`
environment variable. This can be accomplished using the

`k8sutil.GetWatchNamespace` in your Operator.
