SpringCloud-Project deployment based on Docker and Docker-Compose

1. Initialize the environment

1. Uninstall the old version

First, uninstall any old versions of Docker that may be present. If you are not sure whether you have installed it, you can directly execute the following command:

sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine

2. Update the system

Update system information:

sudo yum update -y

3. Install the dependencies required by Docker

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

insert image description here

2. Set up the Docker image source

To speed up downloading, it is recommended to use a domestic Docker image source.

1. Tencent Cloud Image Source

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

2. Alibaba Cloud Image Source

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

3. Tsinghua University Mirror Source

sudo yum-config-manager \
    --add-repo \
    https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

4. Official mirror source

Official mirror sources, that is, foreign mirror sources, are slower and may be blocked.

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

3. Install Docker

1. Install the latest version

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

insert image description here

2. Install the specified version

If you need to install a specific version of Docker, you can first query the list of available versions:

yum list docker-ce --showduplicates | sort -r

Based on the query results, select the required version (for example 26.0.0), and then execute:

sudo yum install -y docker-ce-<VERSION> docker-ce-cli-<VERSION> containerd.io

Replace <VERSION>with the actual version number.

3. Start and set the system to start automatically

sudo systemctl start docker
sudo systemctl enable docker

4. Verify the installation results

docker info

4. Install Docker Compose

1. Add EPEL repository

sudo yum install -y epel-release

insert image description here

2. Install Docker Compose

sudo yum install -y docker-compose

insert image description here

3. Check the version

docker-compose --version

insert image description here

5. Configure the image accelerator

To increase the speed of pulling images, you can configure an image accelerator.

1. Tencent Cloud Image Accelerator

Editing the Configuration File

sudo vim /etc/docker/daemon.json

Add the following content

{
    
    
  "registry-mirrors": [
    "https://mirror.ccs.tencentyun.com"
  ]
}

insert image description here

2. Alibaba Cloud Image Accelerator

Please refer to Configuring Image Accelerator_Container Registry (ACR) to obtain your dedicated accelerator address.

Add accelerator address

sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://<您的阿里云加速器地址>"
    ]
}
EOF

Replace <您的阿里云加速器地址>with the actual address.

3. Restart Docker

sudo systemctl daemon-reload
sudo systemctl restart docker

4. Verify the configuration

docker info

In the output, you should see the configured image accelerator.

6. Upload the SpringCloud project to be deployed

Modify the file according to project requirements and deploy the project to the directory under docker-compose.ymlthe root directory .docker

7. Initialize the project using Docker Compose

1. Set permissions

sudo chmod -R 777 /docker

2. Enter the project directory

cd /docker

insert image description here

3. Create and run all containers in the background

docker-compose up -d

Wait for the image to be downloaded, built, and the container to be started.

insert image description here

You can view the container status with the following command:

# 查看镜像列表
docker images

insert image description here

# 查看所有容器
docker ps -a

insert image description here

# 查看指定容器的日志
docker logs -f <容器名称>

insert image description here
Visit the project address we deployed.

insert image description here

Deployment Success

4. Renewal container

Rebuild and start the container (when the code is changed)

docker-compose up --force-recreate --build -d <服务名称>

insert image description here

Replace <服务名称>with docker-compose.ymlthe service name defined in .

Restart the container (refresh only)

docker restart <容器名称>
