VMUser

The VMUser CRD describes user configuration, its authentication methods basic auth or Authorization header. User access permissions, with possible routing information.

User can define routing target with static config, by entering target url, or with CRDRef, in this case, operator queries kubernetes API, retrieves information about CRD and builds proper url.

Specification#

You can see the full actual specification of the VMUser resource in the API docs -> VMUser.

Also, you can check out the examples section.

Authentication methods#

There are two authentication mechanisms: “Bearer token” and “Basic auth” with username and password. Only one of them can be used with VMUser at one time.

Operator creates Secret for every VMUser with name - vmuser-{VMUser.metadata.name}. It places username + password or bearerToken into data section.

Bearer token#

Bearer token is a way to authenticate user with Authorization header. User defines token field in auth section.

Also, you can check out the examples section.

Basic auth#

Basic auth is the simplest way to authenticate user. User defines username and password fields in auth section.

If username is empty, metadata.name from VMUser used as username.

You can automatically generate password if:

  • Set generatePassword: true field
  • Don’t fill password field

Operator generates random password for this VMUser, this password will be added to the Secret for this VMUser at data.password field.

Also, you can check out the examples section.

Routing#

You can define routes for user in targetRefs section.

For every entry in targetRefs you can define routing target with static config, by entering target url, or with crd, in this case, operator queries kubernetes API, retrieves information about CRD and builds proper url.

Here are details about other fields in targetRefs:

  • paths is the same as src_paths from auth config
  • headers is the same as headers from auth config
  • targetPathSuffix is the suffix for url_prefix (target URL) from auth config

Static#

The static field is the same as url_prefix (target URL) from auth config, it allows you to set a specific static URL.

CRDRef#

The crd field is a more convenient form for specifying the components handled by the operator as auth targets.

User can define routing target with crd config, by entering kind, name and namespace of CRD.

Operator supports following kinds in kind field:

Also, you can check out the examples section.

Additional fields like path and scheme can be added to CRDRef config.

Enterprise features#

Custom resource VMUser supports feature IP filters from VictoriaMetrics Enterprise.

IP Filters#

For using IP filters you need to enable VMAuth Enterprise.

After that you can add ip_filters field to VMUser:

apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
  name: vmuser-ent-example
spec:
  username: simple-user
  password: simple-password

  # using enterprise features: ip filters for vmuser
  # more details about ip filters you can read in https://docs.victoriametrics.com/vmuser.html#enterprise-features
  ip_filters:
    allow_list:
      - 10.0.0.0/24
      - 1.2.3.4
    deny_list:
      - 5.6.7.8

Examples#

apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
  name: example
spec:
  username: simple-user
  password: simple-password
  targetRefs:
    - crd:
        kind: VMSingle
        name: example
        namespace: default
      paths: ["/.*"]
    - static:
        url: http://vmalert-example.default.svc:8080
      paths: ["/api/v1/groups","/api/v1/alerts"]
