High Availability

[irtaza9]

I want to achieve the HA for my services. Is there any way to achieve this by using dokploy?

Hi, yes you can achieve HA using dokploy, however you need a external load balancer, probably in the next weeks i will make a guide, people on discord asked the same, but yes is possible

[Siumauricio]

I'll suggest to use stateless applications instead of trying to achieve HA with databases...

[irtaza9]

we need a guide on HA for applications and databases which will definitely help everyone, Also it will add more value to this amazing product. It is not a big deal to add external lb/HAProxy but your suggested way and guide will make a priority.

[Siumauricio]

For databases I have never tried it, but surely the guide I make will be for applications only.

@Siumauricio any update on this?

I have currently migrated to cloudflare dns and have setup load balancer. I have setup an application (3 replicas) pointing to test domain which is load balanced by cloudflare, one ip mapped to dokploy installed vps for which health monitor is ok, but the ip of the secondary and third master health monitor is not working. The idea is for any reason the first master is down, docker swarm will take over on either secondary or third master so the internet traffic will still get a response. I might be wrong and looking forward to the HA documentation to do it properly. I kindly request to make this a high priority

It would be beneficial to add the usage of swarm and remote server in HA, also a check box to setup replica database whilst setting up the database either within the swarm or remote servers whichever is the correct way to do it

Implementing a complete HA (High Availability) solution, as mentioned before, including shared storage across machines—even for the database, not just the application—would be ideal. Anyway I encountered issues because setting up HA with Docker Swarm for my volumes is quite challenging, and there doesn’t seem to be a "standardized" approach for achieving this.

i found this solution, haven't tested as i have a mysql container running in one of the node, you can try https://github.com/jnidzwetzki/mysql-ha-cloud/blob/main/docs/deployment-docker-swarm.md
