Install the docker environment

Because the Tailchat environment is a bit complicated for beginners, it provides a docker-based one-command environment configuration. But for students who are not familiar with docker, docker itself may also be a kind of complexity.

Therefore, in order to facilitate everyone to quickly build Tailchat, this article is provided as a guide. Students who have a certain understanding of docker can skip this article

This article takes linux centos as an example, the goal is to facilitate the deployment directly on the server. For students who want to use it on other systems (windows, mac), you can refer to the official documentation to install docker

One-command installation of docker​

Officially maintained one-command installation Docker script, suitable for students who don’t like to study details

Execute the following operations in sequence on the server terminal

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

If the installation is successful, you can skip the subsequent content.

Manually install docker and docker compose​

Official document: https://docs.docker.com/engine/install/

# If you have installed docker before, you can execute the following command to delete the old one
sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine
sudo yum install -y yum-utils # yum-utils provides the yum-config-manager command

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

Install docker and docker-compose plugins

sudo yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

PS: docker-compose-plugin provides the docker compose command, the usage is the same as docker-compose

If docker ps shows that the daemon process is not started (Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?), you can execute the following command to start it: sudo systemctl start docker

Install docker-compose separately​

If the purchased server has been pre-installed with docker, if you want to install docker-compose separately, you can read this section:

Official document: https://docs.docker.com/compose/install/

curl -SL https://github.com/docker/compose/releases/download/v2.4.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose # Download binaries
sudo chmod +x /usr/local/bin/docker-compose # give execute permission
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose # Soft link to path, can be called directly
docker-compose --version # The line command returns the version number and the installation is successful

NOTICE​

For historical reasons, docker compose has a docker plugin version and a docker compose standalone version. Generally speaking, docker compose xxx is equivalent to docker-compose xxx
