## 安装与卸载
|
|
|
|
Compose 目前支持 Linux、macOS、Windows 10 三大平台。
|
|
|
|
Compose 可以通过 Python 的包管理工具 pip 进行安装，也可以直接下载编译好的二进制文件使用，甚至直接运行在 Docker 容器中。
|
|
|
|
前两种方式是传统方式，适合本地环境下安装使用；最后一种方式则不破坏系统环境，更适合云计算场景。
|
|
|
|
### PIP 安装
|
|
这种方式是将 Compose 当作一个 Python 应用来从 pip 源中安装。
|
|
|
|
执行安装命令：
|
|
|
|
```bash
|
|
$ sudo pip install -U docker-compose
|
|
```
|
|
|
|
可以看到类似如下输出，说明安装成功。
|
|
```bash
|
|
Collecting docker-compose
|
|
Downloading docker-compose-1.8.0.tar.gz (149kB): 149kB downloaded
|
|
...
|
|
Successfully installed docker-compose cached-property requests texttable websocket-client docker-py dockerpty six enum34 backports.ssl-match-hostname ipaddress
|
|
```
|
|
|
|
安装成功后，可以查看 `docker-compose` 命令的用法。
|
|
```bash
|
|
$ docker-compose -h
|
|
Define and run multi-container applications with Docker.
|
|
|
|
Usage:
|
|
docker-compose [-f=<arg>...] [options] [COMMAND] [ARGS...]
|
|
docker-compose -h|--help
|
|
|
|
Options:
|
|
-f, --file FILE Specify an alternate compose file (default: docker-compose.yml)
|
|
-p, --project-name NAME Specify an alternate project name (default: directory name)
|
|
--x-networking (EXPERIMENTAL) Use new Docker networking functionality.
|
|
Requires Docker 1.9 or later.
|
|
--x-network-driver DRIVER (EXPERIMENTAL) Specify a network driver (default: "bridge").
|
|
Requires Docker 1.9 or later.
|
|
--verbose Show more output
|
|
-v, --version Print version and exit
|
|
|
|
Commands:
|
|
build Build or rebuild services
|
|
help Get help on a command
|
|
kill Kill containers
|
|
logs View output from containers
|
|
pause Pause services
|
|
port Print the public port for a port binding
|
|
ps List containers
|
|
pull Pulls service images
|
|
restart Restart services
|
|
rm Remove stopped containers
|
|
run Run a one-off command
|
|
scale Set number of containers for a service
|
|
start Start services
|
|
stop Stop services
|
|
unpause Unpause services
|
|
up Create and start containers
|
|
migrate-to-labels Recreate containers to add labels
|
|
version Show the Docker-Compose version information
|
|
```
|
|
|
|
之后，可以添加 bash 补全命令。
|
|
|
|
```bash
|
|
$ curl -L https://raw.githubusercontent.com/docker/compose/1.8.0/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose
|
|
```
|
|
|
|
### 二进制包
|
|
官方定义编译好二进制包，供大家使用。这些发布的二进制包可以在 [https://github.com/docker/compose/releases](https://github.com/docker/compose/releases) 页面找到。
|
|
|
|
这些二进制文件，下载后直接放到执行路径下，并添加执行权限即可。
|
|
|
|
例如，在 Linux 和 macOS 平台上。
|
|
|
|
```bash
|
|
$ sudo curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
|
|
$ sudo chmod a+x /usr/local/bin/docker-compose
|
|
```
|
|
|
|
可以使用 `docker-compose version` 命令来查看版本信息，以测试是否安装成功。
|
|
|
|
```bash
|
|
$ docker-compose version
|
|
docker-compose version 1.8.0, build 94f7016
|
|
docker-py version: 1.9.0
|
|
CPython version: 2.7.6
|
|
OpenSSL version: OpenSSL 1.0.1f 6 Jan 2014
|
|
```
|
|
|
|
### 容器中执行
|
|
|
|
Compose 既然是一个 Python 应用，自然也可以直接用容器来执行它。
|
|
|
|
```bash
|
|
$ curl -L https://github.com/docker/compose/releases/download/1.8.0/run.sh > /usr/local/bin/docker-compose
|
|
$ chmod +x /usr/local/bin/docker-compose
|
|
```
|
|
|
|
实际上，查看下载的 `run.sh` 脚本内容，如下
|
|
|
|
```bash
|
|
set -e
|
|
|
|
VERSION="1.8.0"
|
|
IMAGE="docker/compose:$VERSION"
|
|
|
|
|
|
# Setup options for connecting to docker host
|
|
if [ -z "$DOCKER_HOST" ]; then
|
|
DOCKER_HOST="/var/run/docker.sock"
|
|
fi
|
|
if [ -S "$DOCKER_HOST" ]; then
|
|
DOCKER_ADDR="-v $DOCKER_HOST:$DOCKER_HOST -e DOCKER_HOST"
|
|
else
|
|
DOCKER_ADDR="-e DOCKER_HOST -e DOCKER_TLS_VERIFY -e DOCKER_CERT_PATH"
|
|
fi
|
|
|
|
|
|
# Setup volume mounts for compose config and context
|
|
if [ "$(pwd)" != '/' ]; then
|
|
VOLUMES="-v $(pwd):$(pwd)"
|
|
fi
|
|
if [ -n "$COMPOSE_FILE" ]; then
|
|
compose_dir=$(dirname $COMPOSE_FILE)
|
|
fi
|
|
# TODO: also check --file argument
|
|
if [ -n "$compose_dir" ]; then
|
|
VOLUMES="$VOLUMES -v $compose_dir:$compose_dir"
|
|
fi
|
|
if [ -n "$HOME" ]; then
|
|
VOLUMES="$VOLUMES -v $HOME:$HOME -v $HOME:/root" # mount $HOME in /root to share docker.config
|
|
fi
|
|
|
|
# Only allocate tty if we detect one
|
|
if [ -t 1 ]; then
|
|
DOCKER_RUN_OPTIONS="-t"
|
|
fi
|
|
if [ -t 0 ]; then
|
|
DOCKER_RUN_OPTIONS="$DOCKER_RUN_OPTIONS -i"
|
|
fi
|
|
|
|
exec docker run --rm $DOCKER_RUN_OPTIONS $DOCKER_ADDR $COMPOSE_OPTIONS $VOLUMES -w "$(pwd)" $IMAGE "$@"
|
|
```
|
|
|
|
可以看到，它其实是下载了 `docker/compose` 镜像并运行。
|
|
|
|
### 卸载
|
|
如果是二进制包方式安装的，删除二进制文件即可。
|
|
|
|
```bash
|
|
$ sudo rm /usr/local/bin/docker-compose
|
|
```
|
|
|
|
如果是通过 python pip 工具安装的，则可以执行如下命令删除。
|
|
|
|
```bash
|
|
$ sudo pip uninstall docker-compose
|
|
```
|
