docker命令，docker安装其他组件查看docker安装包，卸载docker，docker复制文件，docker服

查看docker安装包

yum list installed | grep docker

出现下图：

Repository epel is listed more than once in the configuration
docker-ce.x86_64                     3:20.10.11-3.el8                        @docker-ce-stable
docker-ce-cli.x86_64                 1:20.10.11-3.el8                        @docker-ce-stable
docker-ce-rootless-extras.x86_64     20.10.11-3.el8                          @docker-ce-stable
docker-scan-plugin.x86_64            0.9.0-3.el8

卸载docker

yum remove docker-ce.x86_64 docker-ce-cli.x86_64  docker-ce-rootless-extras.x86_64 docker-scan-plugin.x86_64

docker复制文件

# 查看容器id
docker ps -a
# 复制容器内文件到本地
docker cp 容器ID:目标文件路径 本地文件路径
# 复制本地文件到容器
docker cp 本地文件路径 容器ID:容器内文件夹

docker服务自启动

# docker服务创建启动时增加参数
docker run –restart=always
# 如果已经启动了，增加自启动
docker update –restart=always <CONTAINER ID>
# docker-compose配置自启动
restart: always
# 关闭自启动
docker update --restart=no <CONTAINER ID>
# 所有容器都关闭
docker update --restart=no $(docker ps -q)

docker安装其他组件

tomcat

在https://hub.docker.com/上找到适合的tomcat版本
然后拉取docker pull tomcat:9.0.58-jdk8
简单启动(不映射任何容器中的文件到主机中)docker run --name tomcat -p 8080:8080 -d tomcat
注意最新版的tomcat可能没有webapps，而是webapps.dist，需要改下名字

docker exec -it tomcat bash
# 进入webapps目录下
mv webapps.dist webapps

zookeeper

docker pull zookeeper
docker run -d --name zookeeper -p 2181:2181 -t zookeeper:3.5.8

kafka

docker pull wurstmeister/kafka:2.12-2.3.1
docker run  -d --name kafka -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092  wurstmeister/kafka:2.12-2.3.1

mysql

# 查看mysql版本
docker search mysql

# 拉取mysql-server
docker pull mysql/mysql-server

# 运行mysql容器
docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql/mysql-server --lower-case-table-names=1

# 进入
docker exec -it mysql bash

mysql -u root -p
# 输入密码 root

# 授权、刷新授权、修改root密码、刷新授权
CREATE USER 'root'@'%' IDENTIFIED BY 'root';
# 更新密码
ALTER USER 'root'@'%' IDENTIFIED BY 'D~INMM9HB)5Da!x';
ALTER USER 'root'@'localhost' IDENTIFIED BY 'D~INMM9HB)5Da!x';
GRANT ALL ON *.* TO 'root'@'%';
flush privileges;
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'D~INMM9HB)5Da!x';
flush privileges;

# 可以连接了

# 查看版本号
select version();

postgres

# 见图一
docker search postgres
# 见图二
docker pull postgres
# 见图三
docker run --name postgres -e POSTGRES_PASSWORD=123456 -p 5432:5432 -d postgres

redis

docker pull redis:latest
docker run -itd --name redis -p 6379:6379 redis  --requirepass 123456@
docker exec -it redis bash
