This article introduces the relevant knowledge of "the process of k8s starting mysql master and slave". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Start two docker, and the service is in mysql master-slave mode

First, you need to build two docker, using the image of mysql5.7 as the base image.

1. Mysql-master Dockerfile

FROM mysql:latestRUN cp / usr/share/zoneinfo/Asia/Shanghai / etc/localtime & & echo "Asia/shanghai" > > / etc/timezoneCOPY mysqld.cnf / etc/mysql/mysql.conf.d/mysqld.cnfCOPY entrypoint.sh / COPY init-master.sh / docker-entrypoint-initdb.d/

Execute the following command in the current directory:

Docker built-t mysql-master:v1.0.

2. Mysql-slave Dockerfile

FROM mysql:latestRUN cp / usr/share/zoneinfo/Asia/Shanghai / etc/localtime & & echo "Asia/shanghai" > > / etc/timezoneCOPY mysqld.cnf / etc/mysql/mysql.conf.d/COPY entrypoint.sh / COPY slave-init.sh / docker-entrypoint-initdb.d/

Execute the following command in the current directory:

Docker built-t mysql-slave:v1.0.

3. Execute the yaml file master of K8s, filename: mysql-master.yaml

Make sure there is a / data/mysql_data directory locally

ApiVersion: v1kind: Podmetadata: name: master-tdbwv labels: name: master-tdbwvspec: volumes:-name: data hostPath: path: / data/mysql_data containers:-name: master-tdbwv image: mysql-master:v1.0 env:-name: MYSQL_ROOT_PASSWORD value: uggTKd3xsIMM-name: MYSQL_REPLICATION_USER value: repl-name: MYSQL_ REPLICATION_PASSWORD value: RQfUjBff ports:-containerPort: 3306 name: master-tdbwv volumeMounts:-name: data mountPath: / var/lib/mysql resources: limits: cpu: 2 memory: 200Mi nodeName: localhost---apiVersion: v1kind: Servicemetadata: name: master-tdbwv labels: name: master-tdbwvspec: type: NodePort ports: -port: 3306 nodePort: selector: name: master-tdbwv

4. Execute the yaml file slave of K8s, filename: mysql-slave.yaml

Make sure there is a / data/mysql_slave_data directory locally

ApiVersion: v1kind: Podmetadata: name: slave-ncrxq labels: name: slave-ncrxqspec: volumes:-name: data hostPath: path: / data/mysql_slave_data containers:-name: slave-ncrxq image: mysql-slave:v1.0 env:-name: MYSQL_ROOT_PASSWORD value: uggTKd3xsIMM-name: MYSQL_REPLICATION_USER value: repl-name: MYSQL_REPLICATION_PASSWORD value: RQfUjBff-name: MYSQL_MASTER_SERVICE_HOST value: 127.0.0.1 ports:-containerPort: 3306 name: slave-ncrxq volumeMounts:-name: data mountPath: / var/lib/mysql resources: limits: cpu: 2 memory: 200Mi nodeName: localhost---apiVersion : v1kind: Servicemetadata: name: slave-ncrxq labels: name: slave-ncrxqspec: type: NodePort ports:-port: 3306 nodePort: selector: name: slave-ncrxq "the process of k8s starting mysql master and slave" ends here Thank you for your reading.
