二、Docker配置

1.使用非root用户管理docker

a. 创建 docker 用户组.

$ sudo groupadd docker

b. 将当前用户添加进 docker 用户组.

$ sudo usermod -aG docker $USER

c. 重启/注销重新登陆生效。

在 Linux 上，您还可以运行以下命令来激活对组的更改

$ newgrp docker

d. 测试不用 sudo运行docker .

$ docker run hello-world

2.配置镜像源

针对Docker客户端版本大于 1.10.0 的用户

sudo vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"]
}

3.配置数据储存位置

{
  "data-root": "/srv/docker-data",
  "storage-driver": "overlay2"

# 创建自定义网桥及配置IP网段, --subnet 可自定义配置所有(保留IP地址)

docker network create --subnet=x.x.x.0/24 netBridgeName(自定义网桥名称)
# 创建容器且指定网络IP

docker run -itd --name [containerName] --network=netBridgeName --ip x.x.x.2 [image]

# 查看docker下网络模式
docker network list

# 删除docker下的网络(删除创建的网桥)
docker rm netBridgeName

5.配置DNS

三、Docekr-Compose安装

1. 二进制安装

1

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

国内加速下载

1

sudo curl -L "https://gh.api.99988866.xyz/https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 赋予执行权限
sudo chmod +x /usr/local/bin/docker-compose
# 检查是否安装成功
docker-compose --version

注意：如果docker-compose安装后命令失败，请检查您的路径。您还可以/usr/bin在路径中创建指向或任何其他目录的符号链接。

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

# 卸载
sudo rm /usr/local/bin/docker-compose

2. 使用pip安装
