discovery.scaleway

discovery.scaleway discovers targets from Scaleway instances and baremetal services.

Usage

river Copy

discovery.scaleway "LABEL" {
    project_id = "SCALEWAY_PROJECT_ID"
    role       = "SCALEWAY_PROJECT_ROLE"
    access_key = "SCALEWAY_ACCESS_KEY"
    secret_key = "SCALEWAY_SECRET_KEY"
}

Arguments

The following arguments are supported:

The role argument determines what type of Scaleway machines to discover. It must be set to one of the following:

• "baremetal": Discover baremetal Scaleway machines.
• "instance": Discover virtual Scaleway instances.

The name_filter and tags_filter arguments can be used to filter the set of discovered servers. name_filter returns machines matching a specific name, while tags_filter returns machines who contain all the tags listed in the tags_filter argument.

no_proxy can contain IPs, CIDR notations, and domain names. IP and domain names can contain port numbers. proxy_url must be configured if no_proxy is configured.

proxy_from_environment uses the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions thereof). Requests use the proxy from the environment variable matching their scheme, unless excluded by NO_PROXY. proxy_url and no_proxy must not be configured if proxy_from_environment is configured.

proxy_connect_header should only be configured if proxy_url or proxy_from_environment are configured.

Blocks

The following blocks are supported inside the definition of discovery.scaleway:

The > symbol indicates deeper levels of nesting. For example, oauth2 > tls_config refers to a tls_config block defined inside an oauth2 block.

tls_config block

The following pairs of arguments are mutually exclusive and can’t both be set simultaneously:

• ca_pem and ca_file
• cert_pem and cert_file
• key_pem and key_file

When configuring client authentication, both the client certificate (using cert_pem or cert_file) and the client key (using key_pem or key_file) must be provided.

When min_version is not provided, the minimum acceptable TLS version is inherited from Go’s default minimum version, TLS 1.2. If min_version is provided, it must be set to one of the following strings:

• "TLS10" (TLS 1.0)
• "TLS11" (TLS 1.1)
• "TLS12" (TLS 1.2)
• "TLS13" (TLS 1.3)

Exported fields

The following fields are exported and can be referenced by other components:

When role is baremetal, discovered targets include the following labels:

• __meta_scaleway_baremetal_id: ID of the server.
• __meta_scaleway_baremetal_public_ipv4: Public IPv4 address of the server.

• __meta_scaleway_baremetal_type: Commercial type of the server.
• __meta_scaleway_baremetal_zone: Availability zone of the server.

When role is instance, discovered targets include the following labels:

• __meta_scaleway_instance_boot_type: Boot type of the server.

• __meta_scaleway_instance_name: Name of the server.
• __meta_scaleway_instance_organization_id: Organization ID that the server belongs to.
• __meta_scaleway_instance_private_ipv4: Private IPv4 address of the server.
• __meta_scaleway_instance_project_id: Project ID the server belongs to.
• __meta_scaleway_instance_public_ipv4: Public IPv4 address of the server.
• __meta_scaleway_instance_public_ipv6: Public IPv6 address of the server.
• __meta_scaleway_instance_region: Region of the server.
• __meta_scaleway_instance_security_group_id: ID of the security group the server is assigned to.
• __meta_scaleway_instance_security_group_name: Name of the security group the server is assigned to.
• __meta_scaleway_instance_status: Current status of the server.
• __meta_scaleway_instance_tags: The list of tags associated with the server concatenated with a ,.
• __meta_scaleway_instance_type: Commercial type of the server.
• __meta_scaleway_instance_zone: Availability zone of the server.

Component health

discovery.scaleway is only reported as unhealthy when given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

discovery.scaleway does not expose any component-specific debug information.

Debug metrics

discovery.scaleway does not expose any component-specific debug metrics.

Example

river Copy

discovery.scaleway "example" {
    project_id = "SCALEWAY_PROJECT_ID"
    role       = "SCALEWAY_PROJECT_ROLE"
    access_key = "SCALEWAY_ACCESS_KEY"
    secret_key = "SCALEWAY_SECRET_KEY"
}

prometheus.scrape "demo" {
    targets    = discovery.scaleway.example.targets
    forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
    endpoint {
        url = PROMETHEUS_REMOTE_WRITE_URL

        basic_auth {
            username = USERNAME
            password = PASSWORD
        }
    }
}

Replace the following:

• SCALEWAY_PROJECT_ID: The project ID of your Scaleway machines.
• SCALEWAY_PROJECT_ROLE: Set to baremetal to discover baremetal machines or instance to discover virtual instances.
• SCALEWAY_ACCESS_KEY: Your Scaleway API access key.
• SCALEWAY_SECRET_KEY: Your Scaleway API secret key.
• PROMETHEUS_REMOTE_WRITE_URL: The URL of the Prometheus remote_write-compatible server to send metrics to.
• USERNAME: The username to use for authentication to the remote_write API.
• PASSWORD: The password to use for authentication to the remote_write API.
