atlas
Atlas, brother of Prometheus.
This is a standalone custom Prometheus service discovery application. It consists of a growing number of discoveries which can be enabled/disabled and configured via a yaml file. The discovered targets are then written into a configmap file, which is consumed by Prometheus.
Architecture overview
Available Discoveries:
- Ironic Nodes
discoveries:
ironic:
refresh_interval: 600 #How often the discovery should check for new/updated nodes.
targets_file_name: "ironic.json" #Name of the file to write the nodes to.
os_auth: # Openstack auth
auth_url: openstack auth url
user: openstack user
password: os user pw
user_domain_name: openstack user_domain_name
project_name: openstack project_name
domain_name: openstack domain_name
- Netbox API
- DCIM-Devices
netbox:
refresh_interval: 600 # How often the discovery should check for new/updated devices.
targets_file_name: "netbox.json" #Name of the file to write the devices to.
netbox_host: "netbox_host_url"
netbox_api_token: "netbox_api_token"
dcim:
devices: #Array of device queries
- custom_labels: #Use to add custom labels to the target
anyLabel: "anyValue"
job: "job_name"
target: 1 #Query Parameters: Any parameters the netbox api ([netbox_url]/api/dcim/devices/) accepts.
role: "role_name"
manufacturer: "cisco"
region: "de1"
status: "1"
- custom_labels: ....
- Virtualization-VMs
netbox:
refresh_interval: 600 # How often the discovery should check for new/updated devices.
targets_file_name: "netbox.json" #Name of the file to write the devices to.
netbox_host: "netbox_host_url"
netbox_api_token: "netbox_api_token"
virtualization:
vm: #Array of vms queries
- custom_labels: #Use to add custom labels to the target
anyLabel: "anyValue"
job: "job_name"
target: 1 #Query Parameters: Any parameters the netbox api ([netbox_url]/api/virtualization/virtual-machines/",) accepts.
manufacturer: "cisco"
region: "de1"
tag: "tag_name"
- custom_labels: ....
Install
A Dockerfile is provided to run it on Kubernetes. All necessary ENV VARs/flags can be figured out running ipmi_sd --help
:
NAME:
atlas - discovers custom services, enriches them with metadata labels and writes them to a file or Kubernetes configmap
USAGE:
atlas [global options]
VERSION:
0.1.7
COMMANDS:
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
- OS_PROM_CONFIGMAP_NAME: name of the configmap, where the discovered nodes should be written to.
- K8S_NAMESPACE: name of the K8s namespace atlas is running in.
- K8S_REGION: name of the k8s region atlas is running in
- LOG_LEVEL: log level atlas should use:
- "debug"
- "error"
- "warn"
- "info"
To figure these out you can also just run it locally.
Either by building via docker using docker build .
and then docker run CONTAINER --help
or directly on bare metal if you have a working go
environment with go run cmd/atlas/main.go --help
.
