Deploy Seata Server By Docker

Precautions

• Please avoid directly pulling the latest version image. The latest version is not necessarily a stable version. To avoid unnecessary problems, please go to docker image warehouse to determine the image version to be pulled.

Quick Start

Start seata-server instance

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

Specify seata-server IP and port to start

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

Docker compose startup

Take docker-compose.yaml for example

version: "3"
services:
   seata-server:
     image: seataio/seata-server:${latest-release-version}
     hostname: seata-server
     ports:
       - "8091:8091"
     environment:
       - SEATA_PORT=8091
       - STORE_MODE=file

Container command line and view logs

$ docker exec -it seata-server sh

$ docker logs -f seata-server

Use custom configuration file

Custom configuration files need to be implemented by mounting files. Mount registry.conf and file.conf on the host to the corresponding directory in the container.

• Specify registry.conf

When using a custom configuration file, the environment variable SEATA_CONFIG_NAME must be specified, and the value needs to start with file:, such as: 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

Among them -e is used to configure environment variables, -v is used to mount the host directory.

• Specify file.conf

If you also need to specify the file.conf configuration file at the same time, you need to change the config configuration in the registry.conf file to the following content. The value of name is the corresponding path in the container.

config {
   type = "file"

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

Environment variables

seata-server supports the following environment variables:

• SEATA_IP

Optional. It specifies the IP started by seata-server. This IP is used when registering with the registration center, such as eureka, etc.

• SEATA_PORT

Optional. It is used to specify the port where seata-server starts. The default port is 8091.

• STORE_MODE

Optional. It is used to specify the transaction log storage method of seata-server, supports db, file, redis (supported by Seata-Server 1.3 and above). The default value is file.

• SERVER_NODE

Optional. It is used to specify the seata-server node ID, such as 1,2,3... The default value is generated based on ip.

• SEATA_ENV

Optional. It is used to specify the seata-server operating environment, such as dev, test, etc. When the service is started, configurations such as registry-dev.conf will be used.

• SEATA_CONFIG_NAME

Optional. It is used to specify the configuration file location, such as file:/root/registry, which will load /root/registry.conf as the configuration file. If you need to specify the file.conf file at the same time, you need to change the value of config.file.name in registry.conf to something like file:/root/file.conf.
