Manually deploy Docker - Simple Application Server - Alibaba Cloud Documentation Center

Docker is an open source application container engine. It provides tools and services to automate the packaging, distribution, and execution of containers. Docker offers benefits such as strong isolation, high portability, and simplified management. This topic describes how to install and use Docker and Docker Compose on a Linux Simple Application Server instance.

Note

For more information about Docker, see Docker Overview.
If you want to quickly deploy a Docker environment, see Quickly deploy Docker.

Preparations

You have created a Linux Simple Application Server instance. For more information, see Create a Simple Application Server instance.
You have added ports 80 and 22 to the inbound rules of the firewall for the Linux Simple Application Server instance. For more information, see Set up a firewall.

Deploy Docker

Remotely connect to the Simple Application Server instance. For more information, see Remotely connect to a Linux server.

Deploy Docker based on the operating system of your server.

Alibaba Cloud Linux 4

Before installing a new version of Docker, uninstall all existing Docker components to prevent potential conflicts and compatibility issues.

Uninstall older versions of Docker

Uninstall older Docker versions, related software packages, and repositories.

#Remove Docker-related sources
sudo rm -f /etc/yum.repos.d/docker*.repo
#Uninstall Docker and related packages
sudo dnf -y remove \  
docker \
moby \
docker-ce \
containerd.io \
docker-ce-rootless-extras \
docker-buildx-plugin \
docker-ce-cli \
docker-compose-plugin

Uninstalling Docker does not automatically remove images, containers, persistent volumes (PVs), or networks. This data is stored in the /var/lib/docker/ directory by default. You must manually delete this directory.

Install Docker.

Recommended method:

# Install the Moby runtime
sudo yum install -y moby

Install Docker Community Edition.

If you are not using an Alibaba Cloud server, replace http://mirrors.cloud.aliyuncs.com with https://mirrors.aliyun.com.

#Add the Docker CE package repository
sudo wget -O /etc/yum.repos.d/docker-ce.repo http://mirrors.cloud.aliyuncs.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i 's|https://mirrors.aliyun.com|http://mirrors.cloud.aliyuncs.com|g' /etc/yum.repos.d/docker-ce.repo

#You must select which CentOS version to install, such as CentOS 9 or CentOS 10, and then replace $releasever with the corresponding version number.
# To use CentOS 9, run:
sudo sed -i 's|$releasever|9|' /etc/yum.repos.d/docker-ce.repo
# To use CentOS 10, run:
sudo sed -i 's|$releasever|10|' /etc/yum.repos.d/docker-ce.repo

#Install Docker Community Edition, the containerd.io container runtime, and the Docker Buildx and Compose plugins
sudo dnf -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

#Note: To switch back to the native Moby component provided by Alibaba Cloud Linux 4, first remove the docker-ce components and disable the CentOS repository.
sudo yum remove -y docker-ce docker-ce-cli
sudo rm -rf /etc/yum.repos.d/docker-ce.repo

Start Docker and enable it to start on boot.

# Start the service and enable it to start on boot
sudo systemctl start docker
sudo systemctl enable docker

# Verify the installation
docker --version  # This will display the installed version

Note

Moby is the default container runtime on this system and will continue to be updated in future versions.
For forward compatibility, older Docker components can still be used but will no longer receive updates.

sudo docker pull nginx:latest
#Create a Dockerfile that sets Nginx as the base image and creates an index.html file that displays "Hello World!" in the web server's root directory.
sudo tee Dockerfile <<-'EOF'
FROM nginx:latest
RUN echo 'Hello World!' > /usr/share/nginx/html/index.html
EOF
#Build the image and name it hello-world
sudo docker build . -t hello-world:latest

Use the web application image to start a container named hello-world.
```
sudo docker run -d -p 80:80 --name hello-world hello-world:latest
```

FAQ

How do I run Docker as a non-root user?

By default, Docker commands require root privileges (executed with sudo). To avoid using sudo for every command and to follow the Principle of Least Privilege, add your current user to the docker group.

Add the current user to the docker group.
```
sudo usermod -aG docker $USER
```
Run newgrp docker to apply the changes to your current shell. You can then use docker commands directly without sudo. For the change to be permanent, you may need to log out and log back in.

Why is http://mirrors.cloud.aliyuncs.com inaccessible?

Symptom: The address http://mirrors.cloud.aliyuncs.com is inaccessible.
Possible cause: Network instability.
Solution: Replace http://mirrors.cloud.aliyuncs.com with https://mirrors.aliyun.com.
To use https://mirrors.aliyun.com, your instance must have a public IP address. For instructions, see Enable Internet access.

Why does the dnf config-manager command fail?

Symptom: When running dnf config-manager on a Linux instance, a deprecation warning appears:

/usr/lib/python3/dist-packages/dnf/const.py:22: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives.

Possible cause: The dnf version is outdated.
Solution: Update the dnf package to the latest version by running sudo dnf update dnf, then try installing Docker again.

Why does the dnf install docker-ce command fail?

Symptom: When running dnf -y install docker-ce on a Linux instance, the following error occurs, indicating a download failure:

(8-9/12): docker-ce-24.0.7-1.el8.x86_64.rpm 38% [================- ] 8.2 MB/s | 38 MB 00:07 ETA
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.
Error: Error downloading packages:
containerd.io-1.6.26-3.1.el8.x86_64: Cannot download, all mirrors were already tried without success.

Possible cause: The package cache is outdated, causing the installation to fail.
Solution: Clear the package cache by running sudo dnf clean packages, then retry the docker installation.

Symptom: When running dnf -y install docker-ce on a Linux instance, the following error occurs, indicating a failure to download metadata:

CentOS- Base                                                                                                                         0.0  B/s |   0  B     00:30    
Errors during downloading metadata for repository 'base':
  - Curl error (6): Couldn't resolve host name for http://mirror.centos.org/os/BaseOS/x86_64/os/repodata/repomd.xml [Could not resolve host: mirror.aliyuncs.com]
  - Curl error (28): Timeout was reached for http://mirror.centos.org/os/BaseOS/x86_64/os/repodata/repomd.xml [Connection timed out after 30000 milliseconds]
  - Curl error (6): Couldn't resolve host name for http://mirror.centos.org/os/BaseOS/x86_64/os/repodata/repomd.xml [Could not resolve host: mirror.cloud.aliyuncs.com]
Error: Failed to download metadata for repo 'base': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Possible cause: You are using a discontinued CentOS 8 repository.

Solution: To resolve this, replace the discontinued CentOS 8 repository with an available one from Alibaba Cloud by following these steps.

# Back up the expired software source.
sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
# Download the Alibaba Cloud-provided CentOS-Base.repo to /etc/yum.repos.d/.
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.aliyuncs.com/repo/Centos-vault-8.5.2111.repo
# Replace the software source address in the Alibaba Cloud source with an address accessible to ECS.
sudo sed -i 's/mirrors.cloud.aliyuncs.com/url_tmp/g' /etc/yum.repos.d/CentOS-Base.repo && sudo sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/CentOS-Base.repo && sudo sed -i 's/url_tmp/mirrors.aliyun.com/g' /etc/yum.repos.d/CentOS-Base.repo
# Clear the old cache and generate a new one.
sudo yum clean all && sudo yum makecache

After completing these steps, retry the docker installation.
