metalctl update check
latest version:v0.8.3 from:2020-08-13T11:55:14Z
local  version:v0.8.2 from:2020-08-12T09:27:39Z
metalctl is not up to date

metalctl update do
# a download with progress bar starts and replaces the binary. If the binary has root permissions please execute
sudo metalctl update do
# instead

Built from project

make
sudo ln -sf $(pwd)/bin/metalctl /usr/local/bin/metalctl

Configuration

Set up auto-completion for metalctl, e.g. add to your ~/.bashrc:

source <(metalctl completion bash)

Set up metalctl config, by first creating the config folder (mkdir -p ~/.metalctl), then set the values according to your installation in ~/.metalctl/config.yaml:

---
current: prod
contexts:
  prod:
    url: https://api.metal-stack.io/metal
    issuer_url: https://dex.metal-stack.io/dex
    client_id: metal_client
    client_secret: 456
    hmac: YOUR_HMAC

Optional you can specify issuer_type: generic if you use other issuers as Dex, e.g. Keycloak (this will request scopes openid,profile,email):

contexts:
  prod:
    url: https://api.metal-stack.io/metal
    issuer_url: https://keycloak.somedomain.io
    issuer_type: generic
    client_id: my-client-id
    client_secret: my-secret

If you must specify special scopes for your issuer, you can use custom_scopes:

contexts:
  prod:
    url: https://api.metal-stack.io/metal
    issuer_url: https://keycloak.somedomain.io
    custom_scopes: roles,openid,profile,email
    client_id: my-client-id
    client_secret: my-secret

Development

For MacOS users, running the tests might throw an error because tests are utilizing go-mpatch in order to manipulate the time.Now function. The patch allows testing with fixed timestamps.

Instead, MacOS users can utilize the make test-in-docker target to execute the tests.
