Creates a proxy server or application-level gateway between localhost and the Kubernetes API server. It also allows serving static content over specified HTTP path. All incoming data enters through one port and gets forwarded to the remote Kubernetes API server port, except for the path matching the static content path.
Syntax
werf kubectl proxy [--port=PORT] [--www=static-dir] [--www-prefix=prefix] [--api-prefix=prefix] [options]
Examples
# To proxy all of the Kubernetes API and nothing else
kubectl proxy --api-prefix=/
# To proxy only part of the Kubernetes API and also some static files
# You can get pods info with 'curl localhost:8001/api/v1/pods'
kubectl proxy --www=/my/files --www-prefix=/static/ --api-prefix=/api/
# To proxy the entire Kubernetes API at a different root
# You can get pods info with 'curl localhost:8001/custom/api/v1/pods'
kubectl proxy --api-prefix=/custom/
# Run a proxy to the Kubernetes API server on port 8011, serving static content from ./local/www/
kubectl proxy --port=8011 --www=./local/www/
# Run a proxy to the Kubernetes API server on an arbitrary local port
# The chosen port for the server will be output to stdout
kubectl proxy --port=0
# Run a proxy to the Kubernetes API server, changing the API prefix to k8s-api
# This makes e.g. the pods API available at localhost:8001/k8s-api/v1/pods/
kubectl proxy --api-prefix=/k8s-api
Options
--accept-hosts='^localhost$,^127\.0\.0\.1$,^\[::1\]$'
Regular expression for hosts that the proxy should accept.
--accept-paths='^.*'
Regular expression for paths that the proxy should accept.
--address='127.0.0.1'
The IP address on which to serve on.
--api-prefix='/'
Prefix to serve the proxied API under.
--append-server-path=false
If true, enables automatic path appending of the kube context server path to each
request.
--disable-filter=false
If true, disable request filtering in the proxy. This is dangerous, and can leave you
vulnerable to XSRF attacks, when used with an accessible port.
--keepalive=0s
keepalive specifies the keep-alive period for an active network connection. Set to 0 to
disable keepalive.
-p, --port=8001
The port on which to run the proxy. Set to 0 to pick a random port.
--reject-methods='^$'
Regular expression for HTTP methods that the proxy should reject (example
--reject-methods=`POST,PUT,PATCH`).
--reject-paths='^/api/.*/pods/.*/exec,^/api/.*/pods/.*/attach'
Regular expression for paths that the proxy should reject. Paths specified here will be
rejected even accepted by --accept-paths.
-u, --unix-socket=''
Unix socket on which to run the proxy.
-w, --www=''
Also serve static files from the given directory under the specified prefix.
-P, --www-prefix='/static/'
Prefix to serve static files under, if static file directory is specified.
Options inherited from parent commands
--as=''
Username to impersonate for the operation. User could be a regular user or a service
account in a namespace.
--as-group=[]
Group to impersonate for the operation, this flag can be repeated to specify multiple
groups.
--as-uid=''
UID to impersonate for the operation.
--cache-dir='~/.kube/cache'
Default cache directory
--certificate-authority=''
Path to a cert file for the certificate authority
--client-certificate=''

--client-key=''
Path to a client key file for TLS
--cluster=''
The name of the kubeconfig cluster to use
--context=''
The name of the kubeconfig context to use (default $WERF_KUBE_CONTEXT)
--disable-compression=false
If true, opt-out of response compression for all requests to the server
--home-dir=''
Use specified dir to store werf cache files and dirs (default $WERF_HOME or ~/.werf)
--insecure-skip-tls-verify=false
If true, the server`s certificate will not be checked for validity. This will make your
HTTPS connections insecure (default $WERF_SKIP_TLS_VERIFY_REGISTRY)
--kube-config-base64=''
Kubernetes config data as base64 string (default $WERF_KUBE_CONFIG_BASE64 or
$WERF_KUBECONFIG_BASE64 or $KUBECONFIG_BASE64)
--kubeconfig=''
Path to the kubeconfig file to use for CLI requests (default $WERF_KUBE_CONFIG, or
$WERF_KUBECONFIG, or $KUBECONFIG). Ignored if kubeconfig passed as base64.
--log-flush-frequency=5s
Maximum number of seconds between log flushes
--match-server-version=false

--profile-output='profile.pprof'
Name of the file to write the profile to
--request-timeout='0'
The length of time to wait before giving up on a single server request. Non-zero values
should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don`t
timeout requests.
-s, --server=''
The address and port of the Kubernetes API server
--tls-server-name=''

hostname used to contact the server is used

--vmodule=
comma-separated list of pattern=N settings for file-filtered logging (only works for
the default text log format)
--warnings-as-errors=false
