What is Docker? Does it support remote desktop?

As a representative of container technology, Docker has attracted much attention and is widely used in recent years. Although the container technology solution created by Docker has made the application deployment process easier, more efficient and more flexible, we may also encounter some problems during use. Among them, some users raised a question: Does Docker support remote desktop? So, what's the answer?

What is Docker?

Docker is a lightweight virtualization technology based on the Linux kernel that can provide an effective method of deploying applications. Docker uses container (Containers) technology to package the application itself and the required running environment to form an independent running environment so that the application can run on different machines.

Docker and Remote Desktop

Remote desktop means that users use remote connection software to log in to a remote computer locally and control the remote computer through desktop monitors, keyboards and other devices. This can play a big role in practical applications. For example, when an administrator needs to perform management operations on the server, he can remotely manage other people's machines through Remote Desktop.

For Docker, can it also support remote desktop? Since Docker container technology can only provide the running environment of the application, it theoretically does not support remote desktop. However, there are some tricks that can be used to implement remote desktop functionality in actual situations.

Docker supports remote desktop implementation method

To implement the remote desktop function of the Docker container, you need to install the VNC Server on the external server, and then install the VNC Client inside the Docker container. In this way, you can use remote desktop in a Docker container. The specific steps are as follows:

1. Install VNC Client in the Docker container

To use remote desktop, you first need to install the VNC client in the Docker container. Run the following command inside the container to start the VNC Client:

# 安装VNC客户端
apt-get install -y xvnc4viewer

2. Install VNC Server on the external server

After installing the VNC client inside the Docker container, you need to install it on the external server Install VNC Server on. In Ubuntu, VNC Server can be installed using the following command:

# 安装VNC服务端
apt-get install -y vnc4server

3. Start VNC Server

Start VNC Server by following the steps:

# 设置VNC密码
vncpasswd

# 启动VNC Server
vncserver

4. Login to VNC Server

After running VNC Server, you can use tools such as VNC Viewer to connect to the remote computer and enter the VNC password to log in.

5. Log in to the Docker container

After completing the above steps, you can remotely log in to the Docker container through VNC Viewer and use remote desktop operations. It should be noted that when using remote desktop to operate a Docker container, operations within the container will affect the entire container.

Summary

In practical applications, Docker containers can support remote desktop through some techniques. However, it should be noted that for Docker containers, this is just a hack and is not applicable in a production environment, because the container should be an independent, self-contained application unit. In actual enterprise applications, remote management needs can be achieved by using other professional remote desktop software.
