1 - Installed Ubuntu
2 - installed Docker
3 - Pulled docker image
4 - Ran sudo docker run -d --name bitwarden -v /bw-data/:/data/ -p 80:80 mprasil/bitwarden:latest

this was the error I received (sorry if this is obvious, I'm pretty new to linux):
bitwarden_admin@LIASWARDEN:~$ sudo docker run -d --name bitwarden -v /bw-data/:/data/ -p 80:80 mprasil/bitwarden:latest

@BlackDex commented on GitHub (Feb 16, 2019):

Docker wanted to create the path /bw-data, but wasn't allowed to do so because of rights or the / filesystem is a read-only file system for some reason.
What happens if you try to create that folder your self?
sudo mkdir /bw-data
Does that generate an error also?
If not, what happens when you do the docker run again after creating the folder?
