Docker installation seata tutorial

We all know n kinds of processing solutions for distributed transactions, but the more useful one belongs to seata. Seata is an open source distributed transaction solution dedicated to providing high-performance and easy-to-use distributed transaction services. Seata will provide users with AT , TCC , SAGA and XA transaction modes to create a one-stop distributed solution for users.

• No intrusion to the business: that is, to reduce the intrusion of the distributed transaction problem brought about by the micro-service on the technical architecture to the business
• High performance: reduce performance consumption caused by distributed transaction solutions

Several terms of seata:

• TC (Transaction Coordinator) : Transaction coordinator. Manage the state of the global branch transaction for the commit and rollback of the global transaction.
• TM (Transaction Manager) : transaction manager. Used to start, commit or rollback a transaction.
• RM (Resource Manager) : Resource Manager. It is used for resource management on branch transactions, registers branch transactions with TC , reports the status of branch transactions, and receives commands from TC to commit or roll back branch transactions.

5. Shut down and remove old containers

docker stop xxxx

docker rm xxxx

6. Restart the new container

docker run -d --restart always --name seata-server -p 8091:8091 -v /config/docker-data/seata/seata-server -e SEATA_IP=[公网ip] -e SEATA_PORT=8091 seataio/seata-server

Then you can carry out related operations in the project, happy
