首先，删除旧版本:

如果通过apt-get安装

sudo apt-get remove docker-compose

如果通过curl安装

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

如果通过pip安装

pip uninstall docker-compose

然后在GitHub的发布页面上找到最新版本，或者通过卷曲API并使用grep或jq从响应中提取版本(感谢dragon788, frbl和Saber Hayati的这些改进):

# curl + grep
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*\d')

# curl + jq
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)

最后，下载到您最喜欢的$ path可访问的位置，并设置权限:

DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION

下面是另一个使用curl和sed安装最新版本docker-compose的联机程序。

curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose

Centos / RHEL

如果您正在使用x86-64架构的Centos7，请遵循下面我的回答。这个答案也可以在我的github中找到。

停止你的Docker容器

我注意到其他答案并没有谈到在尝试优雅地升级之前停止docker容器/图像实例。假设是不可避免的，但代价可能很高。我们继续前进!

更新Docker-Compose的选项

如果您首先使用Curl命令下载并安装docker-compose，则有两个选项可以升级docker-compose。

使用Curl、jq包和Github的直接URL到docker-compose存储库。 使用Curl、Sed和Github的直接URL到docker-compose存储库。

注意:下面的一些命令需要“sudo”权限。

示范

下面的脚本被保存到一个名为“update_docker_composition .sh”的文件中。您需要赋予该文件可执行权限。

像这样:

chmod +x update_docker_compose.sh

docker_docker_composition .sh文件内容:

#!/bin/bash

# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022

# Stop current docker container running
docker stop containerID

# Remove current docker network running
docker rm containerID

# Remove image of target application(s)
docker image rm imageID

# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f

# This step depends on the jq package. 
# Uncomment jq package installation command below if using Centos7 x86-64.
# sudo yum install jq

# Declare variable to get latest version of docker-compose from github repository
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)

# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'

# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)

# Execute curl command to carry download and installation operation
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$get_local_os_build -o $target_install_dir

# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir

# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)

使用特定于您的环境的变量编辑脚本

上面的脚本有几个变量，您需要使用特定于docker环境的值进行编辑。例如，您需要将容器ID和映像ID替换为以下命令输出的值。

docker ps

and

docker images output

一旦您完成了文件的创建(包括编辑)。切换到包含该文件的目录。例如，如果您在/home/username/script/update_docker_compose.sh中创建文件

cd /home/username/script

最后，执行以下命令运行脚本

./update_docker_compose.sh

选项2

创建一个名为update_docker_composition .sh的脚本文件

编辑文件，添加如下内容:

#!/bin/bash

# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022

# Stop current docker container running
docker stop containerID

# Remove current docker network running
docker rm containerID

# Remove image of target application(s)
docker image rm imageID

# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f

# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'

# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)

# Execute curl and sed command to carry out download and installation operation
# compose_latest_version=$(curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$get_local_os_build") -o $target_install_dir

# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir

# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)

使用特定于您的环境的变量编辑脚本

上面的脚本还有一些变量，您需要使用特定于docker环境的值进行编辑。例如，您需要将容器ID和映像ID替换为以下命令输出的值。

docker ps

and

docker images output

一旦您完成了文件的创建(包括编辑)。切换到包含该文件的目录。例如，如果您在/home/username/script/update_docker_compose.sh中创建文件

cd /home/username/script

最后，执行以下命令运行脚本

./update_docker_compose.sh

如果以上方法对你不起作用，那么参考这个答案:https://stackoverflow.com/a/40554985

curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" > ./docker-compose
sudo mv ./docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

如果你安装了pip，升级你可以使用:

 pip install --upgrade docker-compose

或者像Mariyo在pip3中明确指出的那样:

 pip3 install --upgrade docker-compose

这些解决方案大多已经过时，或者让您安装旧版本。 安装最新版本

sudo apt  install jq

DOCKER_COMPOSE_VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)

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