Ansible roles and playbooks for Victoria Metrics.

Roles are published in ansible galaxy: https://galaxy.ansible.com/ui/namespaces/victoriametrics/

Install collection:

ansible-galaxy collection install victoriametrics.cluster

Collection includes the following roles:

• single - installs and configures VictoriaMetrics single node
• vmagent - installs and configures vmagent
• vmalert - installs and configures vmalert
• vmselect - installs and configures vmselect
• vmstorage - installs and configures vmstorage
• vminsert - installs and configures vminsert
• vmauth - installs and configures vmauth

See cluster and single playbooks for examples of how to use these roles.

Deprecated roles:

• docker - role for docker installation
• load_balancer - nginx setup for load balancing between select and insert nodes
• cluster - installs and configures VictoriaMetrics cluster running in docker

These roles are deprecated in favor of roles for each component. They are still available in the collection, but will be removed in future releases. Note that per-component roles are using binary releases of VictoriaMetrics, while cluster role is using docker images.

Cluster deployment example is available in playbooks/cluster.yml. The playbook deploys VictoriaMetrics cluster and vmauth to act as a load balancer and authentication proxy. See inventory for example of inventory file.

Here is a diagram of the cluster deployment:

It's also possible to use molecule scenario to create a local cluster for testing. See molecule directory for details. The scenario uses docker as a driver and sets up a container for each component. The scenario can be deployed by using make molecule-converge-cluster-integration command.

In order to set up development environment, you need to have docker, python and make installed. Run make init-venv to create virtual environment and install required packages for linting and testing with molecule.

Please, note that cluster role is tested with vagrant and libvirt provider and requires vagrant to be installed.

Refer to Makefile for available commands for linting and molecule testing.
