`MCS` will authenticate against `Mkube`using bearer tokens via HTTP `Authorization` header. The user will provide this token once in the login form, MCS will validate it against Mkube (list tenants) and if valid will generate and return a new MCS sessions with encrypted claims (the user Service account token will be inside the JWT in the data field) Kubernetes The provided `JWT token` corresponds to the `Kubernetes service account` that `Mkube` will use to run tasks on behalf of the user, ie: list, create, edit, delete tenants, storage class, etc. Development If you are running mcs in your local environment and wish to make request to `Mkube` you can set `MCS_M3_HOSTNAME`, if the environment variable is not present by default `MCS` will use `"http://m3:8787"`, additionally you will need to set the `MCS_MKUBE_ADMIN_ONLY=on` variable to make MCS display the Mkube UI Extract the Service account token and use it with MCS For local development you can use the jwt associated to the `m3-sa` service account, you can get the token running the following command in your terminal: ``` kubectl get secret $(kubectl get serviceaccount m3-sa -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode ``` Then run the mcs server ``` MCS_M3_HOSTNAME=http://localhost:8787 MCS_MKUBE_ADMIN_ONLY=on ./mcs server ``` Self-signed certificates and Custom certificate authority for Mkube If Mkube uses TLS with a self-signed certificate, or a certificate issued by a custom certificate authority you can add those certificates usinng the `MCS_M3_SERVER_TLS_CA_CERTIFICATE` env variable ```` MCS_M3_SERVER_TLS_CA_CERTIFICATE=cert1.pem,cert2.pem,cert3.pem ./mcs server ````
