If you’re seeing the error “Cannot connect to the Docker daemon. Is the docker daemon running on this host?”, you can do a few things to resolve it.
First, check that the Docker service is running. You can do this by opening the Services control panel and looking for the Docker service. If it’s not running, start it.
Next, check that the Docker daemon is running by running the command docker info. If you see an error message, then the daemon is not running.
Finally, make sure that you have permission to access the Docker daemon. By default, only members of the docker group can access the daemon. You can either add your user to the docker group, or change the permissions on the Docker socket so that any user can access it.
What is Docker?
Docker is a tool that can be used to create, deploy, and run applications using containers. Containers allow you to package an application with all of the dependencies it needs so that it can run quickly and reliably on any computer.
Docker is used by developers and system administrators to create, deploy, and run applications in containers. Developers use Docker to package up an application with all of the necessary dependencies so that it can be deployed quickly and reliably on any computer. System administrators use Docker to create and manage containers that isolate applications from each other on a shared computer.
Docker is open source, and you can find the source code on GitHub.
What is the error?
The error message “Couldn’t connect to Docker daemon at http+docker://localhost – is it running?” is produced when the Docker client cannot connect to the Docker daemon.
This can happen for a number of reasons, such as:
-The Docker daemon is not running.
-The Docker daemon is not running on the default socket.
-There is a firewall blocking access to the Docker daemon.
To resolve this error, make sure that the Docker daemon is running and that you can access it from the host machine.
How to fix the error?
If you’re getting the “error couldnt connect to docker daemon at httpdockerlocalhost is it running” error, it means that your computer can’t communicate with the Docker daemon. This usually happens because of a misconfiguration in the Docker client or server.
Here are a few ways to fix the problem:
- Check that the Docker daemon is running. You can do this by running “docker ps” from the command line. If the daemon is running, you should see a list of containers.
- Check that the Docker client and server are using the same version of the Docker protocol. You can do this by running “docker version” from the command line. The client and server versions should match.
- Check that your user has permission to access the Docker daemon. On Linux systems, you can do this by adding your user to the “docker” group.
If you’re having trouble connecting to your docker daemon, make sure that it is running. Try checking the status of the daemon with the following command: systemctl status docker.
