Clustering / High Availability (beta)¶
This guide explains how to use Træfik in high availability mode.
In order to deploy and configure multiple Træfik instances, without copying the same configuration file on each instance, we will use a distributed Key-Value store.
You will need a working KV store cluster. (Currently, we recommend Consul .)
File configuration to KV store migration¶
We created a special Træfik command to help configuring your Key Value store from a Træfik TOML configuration file.
Please refer to this section to get more details.
Deploy a Træfik cluster¶
Once your Træfik configuration is uploaded on your KV store, you can start each Træfik instance.
A Træfik cluster is based on a manager/worker model.
When starting, Træfik will elect a manager. If this instance fails, another manager will be automatically elected.
