Troubleshooting installation on macOS
Issues when connecting to Memgraph
docker run -it memgraph/memgraph-platform
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 7444:7444 -p 3000:3000 memgraph/memgraph-platform
Issues with connecting mgconsole to the database
docker run -it --entrypoint=mgconsole memgraph/memgraph-platform --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 Networking features in Docker Desktop for Mac 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/memgraph-platform --host HOST
