Explore the solution to the problem that Idea cannot connect to docker

When developing with Idea, we often encounter situations where we need to connect to Docker, but sometimes we encounter the problem of being unable to connect to Docker, which troubles developers very much. This article will introduce how to solve the problem of Idea connecting to Docker to help developers save themselves troubles.

1. Docker installation and settings

First, we need to ensure that Docker is installed and set up normally. After installing Docker, you need to run the following command in the terminal: sudo usermod -aG docker $USER. Run docker run hello-world again to test whether it is running normally. If you encounter permission issues or Docker does not start properly, you need to check the settings.

2. Idea settings

If the Docker settings are correct but Idea still cannot connect to Docker, you need to check the Idea configuration.

1. First, you need to download the Docker plug-in in Idea, search for the Docker plug-in in Settings > Plugins > Marketplace and install it. After restarting Idea, the plug-in will be automatically enabled.
2. Then, configure Docker in Settings > Build, Execution, Deployment > Docker. Select the remote Docker on the Docker server and enter the Docker address and port in the TCP socket. The default port is 2375.
3. Finally, you can configure the SSH connection in Settings > Tools > SSH Configurations to connect to the remote Docker. After setting up, you can connect to Docker in Idea and develop.

3. Problem Solving

If the above operations still cannot solve the problem of Idea connecting to Docker, you can try the following methods:

1. Check the Docker image and Whether the container is started. You can run docker images and docker ps -a in the terminal to check.
2. Check if the Docker daemon is started. You can run the sudo systemctl status docker command in the terminal to check.
3. Check the Docker daemon's logs to see if there are any errors. You can run the sudo journalctl -u docker.service command in the terminal to view it.

4. Summary

This article introduces the solution to the problem that Idea cannot connect to Docker. First, you need to confirm that Docker is installed and configured correctly, install the Docker plug-in in Idea and configure it, and finally try other solutions. I hope it will be helpful to developers when developing with Idea.
