docker+mysql(8.0.15)+node.js(hapi.js)構建容器(命令行)
安裝docker, 準備一個node.js項目,項目中包含數據庫配置。
一、將node.js項目創建為image
在項目中創建.dockerignore文件和dockerfile文件(https://github.com/hanxiaoer1992/docker_nodejs_cmd)
cd 項目文件夾下(cd ....../docker_nodejs_cmd)
docker image build -t dockertest:0.0.1 .
二、拉取mysql
docker pull mysql
三、構建容器互聯網絡
docker network create -d bridge network-name
四、運行image: mysql, dockertest:0.0.1
docker run --rm --name mysql --network network-name -e MYSQL_ROOT_PASSWORD=mysqlPassword -d -it -p 3307:3306 mysql
(容器停止後自動刪除,不會保留mysql數據)
進入mysql命令行:docker exec -it mysql /bin/bash
mysql -uroot -pmysqlPassword
因‘root‘@‘%‘已在數據庫中,alter user ‘root‘@‘%‘ identified with mysql_native_password by ‘mysqlPassword‘;
(如不更改會報Client does not support authentication protocol requested by server; consider upgrading MySQL client, 因mysql升級後密碼機制改變)
grant all privileges on *.* to ‘root‘@‘%‘ with grant option;
flush privileges;
創建數據庫:
create database dockerTest;
use dockerTest;
create table test(id int(11) auto_increment, name varchar(40), primary key (id) )default charset=utf8;
insert into test (name) values (‘docker-test‘);
exit退出,或另外打開一個命令行
docker container run --rm --name testplay -it -p 1000:3000 --network network-name --link mysql:mysql -e DATABASE_HOST=mysql -e DB_USER=root dockertest:0.0.1 /bin/bash
npm start
