Melangkah-oleh-step Solution for HA Deployment

Implementing hililability in Docker acculves setting up multiple nodes, deploding voculinan with replication, and configbaiming. Thee following stephere outline a typical enas:

1.

Inisialize a Docker Swarm to manaje multiple nodes. Use the compod 1; FLT: 0: 3; on the manajer Ande join worker nodes with thae provided token.

Deploy Services with Replication

Create a servie with multiple replicas to ensure redundancy.
