Install Docker-Compose on Linux CentOS6.8

Install Docker-Compose on Linux CentOS6.8

Try to change to CentOS7 to run docker

1. Run the following command to download the latest version of Docker Compose

curl -L https://github.com/docker/compose/releases/download/1.5.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

Note that the version is 1.5.2, the latest version runs on CentOS6.8 and returns the following error
docker-compose: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/_MEIXH1zkM/libz.so .1)

2. Give executable permission to the binary file application

sudo chmod +x /usr/local/bin/docker-compose

3. Test installation

$ docker-compose --version
docker-compose version 1.5.2, build 9e633ef

The following are mainly from CentOS6.x to install Docker and Docker Compose

4. Docker Compose version problem

When running docker-compose build, we will be prompted that our Docker version is too low and require an upgrade of Docker.
The current docker version is 1.7.1, and the docker-compose version is 1.5.2

Five, docker-compose.yml problem

V1 version of docker-compose.yml is only supported up to docker-compose 1.6.x. Later versions of docker-compose no longer support the V1 version of docker-compose.yml. The main difference in the format of the docker-compose.yml file
that needs to be changed to V1 V1 is:

• no version declaration at the beginning
• no services declaration
• does not support depends_on
• Named volumes, networks, build arguments declarations are not supported
• I haven't used other ones, so I didn't study the difference carefully.

Let's take an example to be more intuitive!

V2 版本的 docker-compose.yml

version: "2"
services:
  redis:
    image: "redis:alpine"
    ports:
      - "6389:6379"
    volumes:
      - "./data/redis/data:/data"
  mysql:
    build: ./builds/mysql
    ports:
      - "3386:3306"
    volumes:
      - "./data/mysql/data:/var/lib/mysql"
      - "./data/mysql/conf:/etc/mysql/conf.d"
    restart: always   
    environment:
      MYSQL_DATABASE: solar
      MYSQL_USER: root
      MYSQL_PASSWORD: Huofigo2015
      MYSQL_ROOT_PASSWORD: Huofigo2015
  api:
    depends_on:
      - mysql
      - redis
    build:
      context: ./builds/api
    ports:
      - "8388:8080"
    volumes:
      - "./target/solar-app-0.0.1-SNAPSHOT.jar:/app/solar-app.jar"
    entrypoint:
      - "java"
      - "-jar"
      - "/app/solar-app.jar"
    restart: always

改成 V1 版本的 docker-compose.yml 后

redis:
 image: "redis:alpine"
 ports:
   - "6389:6379"
 volumes:
   - "./data/redis/data:/data"
mysql:
 build: ./builds/mysql
 ports:
   - "3386:3306"
 volumes:
   - "./data/mysql/data:/var/lib/mysql"
   - "./data/mysql/conf:/etc/mysql/conf.d"
 restart: always
 environment:
   MYSQL_DATABASE: solar
   MYSQL_USER: root
   MYSQL_PASSWORD: Huofigo2015
   MYSQL_ROOT_PASSWORD: Huofigo2015
api:
 build: ./builds/api
 ports:
   - "8388:8080"
 volumes:
   - "./target/solar-app-0.0.1-SNAPSHOT.jar:/app/solar-app.jar"
 links:
   - mysql
   - redis
 entrypoint:
   - "java"
   - "-jar"
   - "/app/solar-app.jar"
 restart: always
