-bash: docker-compose: command not found

I encountered this problem when using Docker to build a Nacos container: the docker-compose tool was not installed.

The usefulness of docker-compose is mainly reflected in the following aspects:

Quickly set up a development environment: Use docker-compose to quickly set up a development environment. For example, a project may require multiple services, such as web applications, databases, etc. Use docker-compose to quickly create and start these services, improving development efficiency. .

Container orchestration: docker-compose can be used for container orchestration to achieve automated deployment and expansion of containers by defining the startup sequence and dependencies of multiple containers.

Rapid deployment: Use docker-compose to package multiple services into an executable file to achieve rapid deployment and startup of services.

Container cluster management: docker-compose can be used to manage container clusters and realize automated management and monitoring of containers by defining startup parameters and configurations for multiple containers.

In short, docker-compose is a service orchestration tool for Docker, mainly used to build and run complex applications composed of multiple services.

1.Installation`pip3`

Installing docker-compose tools requires the use of Python package management commands, so you need to install pip tools first.

I am using 银河麒麟系统 and encountered a new problem during the installation process: 错误：没有任何匹配: python-pip

Then I searched again and only two results appeared. , the first one I chose to install here, it can be used normally anyway.

# 安装python-pip-doc.noarch
yum -y install python-pip-doc.noarch

The installation has been successful at this point. Let’s upgrade pip and find that the pip command is still not found, but the executable commands in the system are pip3; After upgrading here, you can use the pip command. If you don’t upgrade, just use pip3 directly.

# 升级pip
pip3 install --upgrade pip

2. Install docker-compose tool

pip3 install docker-compose

Check if the installation is successful

docker-compose -v

If the following content appears, the installation is successful:
