Troubleshooting installation on Windows

Issues with loading Memgraph​

docker load -i memgraph.tar.gz

Error during connect: This error may indicate that the docker daemon is not running.​

Run the Docker Desktop application and wait for it to load fully.

Error response from daemon: open \\.\pipe\docker_engine_linux: The system cannot find the file specified.​

Reload the Docker Desktop application and wait for it to load fully.

Unsupported os linux​

You need to download the Windows Subsystem for Linux, and enable experimental features in Docker Desktop, under "Settings -> Docker Engine", put "experimental" to true.

Issues when connecting to Memgraph​

docker run -it memgraph

While this command will start a Memgraph instance, not publishing the port will cause problems when trying to connect to the database via Memgraph Lab or mgconsole. To avoid this, you should publish the container's port to the host using the -p flag and by specifying the port:

docker run -it -p 7687:7687 -p 3000:3000 memgraph

Issues with connecting mgconsole to the database​

docker run -it --entrypoint=mgconsole memgraph --host HOST

Although unlikely, sometimes there are issues with connecting mgconsole to the Docker Container’s IP address because it is running on a custom IP rather than localhost. This problem is most often accompanied with the following error:

Connection failure: Couldn't connect to 127.0.0.1:7687!

To fix this issue, just replace HOST from the first command with host.docker.internal. To find out more about networking in Docker, take a look at this guide.

Find the IP address of a Docker Container​

Although unlikely, some users might experience minor difficulties after the Docker installation. Instead of running on localhost, a Docker container for Memgraph may be running on a custom IP address. Fortunately, that IP address can be found as follows:

1. Determine the ID of the Memgraph Container by issuing the command docker ps. The user should get an output similar to the following:

CONTAINER ID    IMAGE       COMMAND                  CREATED
9397623cd87e    memgraph    "/usr/lib/memgraph/m…"   2 seconds ago

At this point, it is important to remember the container ID of the Memgraph Image. In our case, that is 9397623cd87e.

2. Use the this ID to retrieve the IP address of the Container:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 9397623cd87e

The command above will yield the IP address that should be used when connecting to Memgraph via Memgraph Lab or mgconsole as described in the querying section. Just replace HOST from the following command with the appropriate IP address:

docker run -it --entrypoint=mgconsole memgraph --host HOST
