Docker

常用命令

  • 查看所有容器 docker ps -a

  • 本地下载镜像并上传至ecs

    docker run [image]
docker save [image] -o [/path/xxx.tar]
上传ecs
docker load -i [xxx.tar]

nginx

下载镜像

处理外部挂载的配置文件

1. 先创建外部挂载的文件
如ngix.conf
mkdir -p /[your root]/nigx/conf/nginx.conf
mkdir -p /[your root]/nigx/logs
mkdir -p /[your root]/nigx/html
mkdir -p /[your root]/nigx/conf.d

2. 启动一个容器
 docker run --name nginx -p 3001:80 -d nginx
 
 3.拷贝nginx容器对应的文件默认配置
docker cp nginx:/etc/nginx/nginx.conf /opt/docker/nginx/conf/nginx.conf
docker cp nginx:/etc/nginx/conf.d /opt/docker/nginx/conf.d
docker cp nginx:/usr/share/nginx/html /opt/docker/nginx
docker cp nginx:/etc/ssl /home/nginx/  (ssl证书配置)

4. 删除临时容器
  docker stop ngix 
  docker rm ngix

创建容器并运行

docker run \
-p 80:80 \
--name nginx \
-v /home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /home/nginx/conf.d:/etc/nginx/conf.d \
-v /home/nginx/logs:/var/log/nginx \
-v /home/nginx/html:/usr/share/nginx/html \
-v /home/nginx/ssl:/etc/ssl \ 
-d nginx:latest

修改Nginx配置

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {
        listen     80;
        server_name       localhost;

        location / {
            proxy_pass  http://127.0.0.1:3030;
        }
    }
}

MySql

docker run \
-p 3307:3306 \
--name isaac_sql \
-e TZ=Asia/Shanghai \
-e MYSQL_ROOT_PASSWORD=[密码] \
-d mysql \
--character-set-server=utf8mb4 \
--collation-server=utf8mb4_unicode_ci

Spring

打包项目生成jar包

1. maven -> lifecycle-> clean
2. maven -> lifecycle-> package

dockerfile

FROM adoptopenjdk/openjdk11
COPY babywhat-0.0.1-SNAPSHOT.jar bb.jar
RUN bash -c "touch /bb.jar"
EXPOSE 8088
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' > /etc/timezone
ENTRYPOINT ["java", "-jar","bb.jar"]

将dockerfile和jar包放在同一目录下

build dockerfile构建一个镜像

docker build -t [镜像名称] -f [dockerfile路径] .

docker build -t appserver -f ./appservice.dockerfile .
# -f 是找到本地路径下面的dockerfile文件。如果不是默认DockerFile.dockerfile命名的文件则必须要-f

启动容器

docker run -d --name [容器名称] -p 8088:8088 [镜像名称]
# -p 8090:8090  宿主机端口:容器内部端口

Redis

https://www.cnblogs.com/virtulreal/p/16228206.html

docker run \
--name redis \
--restart unless-stopped \
-p 6379:6379 \
-p 8011:8001 \
-e REDIS_ARGS="--requirepass test" \
-d redis

Next

通过nextjs提供的dockerfile进行部署
