• Pull the image

docker pull israiloff/lvim:latest

• Run the container with only necessary ports

docker run -it -d -p 33235:33235 --name lvim israiloff/lvim:latest

• Run the container with additional ports and access to docker itself

docker run -it -d -p 33235:33235 -p 8090-8099:8090-8099 -v /var/run/docker.sock:/var/run/docker.sock --name lvim israiloff/lvim:latest

Port 33235 is used for the markdown preview server. Ports 8090-8099 are additional ports for debugging and testing.
