Deploy Seata Server By Docker

Quick Start

Start a seata-server instance

$ docker run --name seata-server -p 8091:8091 seataio/seata-server:1.4.2

Specify server IP and port

$ docker run --name seata-server \
        -p 8091:8091 \
        -e SEATA_IP=192.168.1.1 \
        -e SEATA_PORT=8091 \
        seataio/seata-server

Docker compose

Example of docker-compose.yaml

version: "3"
services:
  seata-server:
    image: seataio/seata-server
    hostname: seata-server
    ports:
      - "8091:8091"
    environment:
      - SEATA_PORT=8091
      - STORE_MODE=file

Access container and view log

$ docker exec -it seata-server sh
$ docker logs -f seata-server

Using custom configuration file

Custom configuration implement by mount registry.conf and file.conf to container.

  • Specify registry.conf

The environment variableSEATA_CONFIG_NAME is required when use a custom configuration , and the value must be started with file: like file:/root/seata-config/registry:

$ docker run --name seata-server \
        -p 8091:8091 \
        -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
        -v /User/seata/config:/root/seata-config  \
        seataio/seata-server

The param -e specify environment, and the param -v specify mount volume.

  • Specify file.conf

If you need specify file.conf, just modify config like below in registry.conf file:

config {
  type = "file"

  file {
    name = "file:/root/seata-config/file.conf"
  }
}
