Question

mongodb docker container start failed with errors: IllegalOperation: Attempted to create a lock file on a read-only directory: /data/db, terminating
I use offical mongodb Dockerfile to build the container, and use docker-compose to start it.
Here is my Dockerfile:
FROM ubuntu:bionic
# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
RUN groupadd -r mongodb && useradd -r -g mongodb mongodb

CMD ["mongod"]
and docker-compose below:
mongodb:
build: ./dockerfiles/mongodb
volumes:
- ./data/mongodb/db:/data/db
- ./data/mongodb/configdb:/data/configdb
ports:
- 7017:27017
environment:
- MONGO_INITDB_ROOT_USERNAME=super
- MONGO_INITDB_ROOT_PASSWORD=123456
restart: always
I expect the container start successfully. But i got failure with :IllegalOperation: Attempted to create a lock file on a read-only directory: /data/db, terminating
If i remove volumes sections, It works!
The host is ubuntu18.04, and /data is writeable!

I had solved my problem le 老铁!
AS i use vmware to start an Ubuntu server, and shared a folder with windows 7. The container volume on the shared folder.
check the inspect information of the mongodb container.
"Mounts": [
{
"Type": "bind",
"Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/configdb",
"Destination": "/data/configdb",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
},
{
"Type": "bind",
"Source": "/mnt/hgfs/ubuntu/dockers/data/mongodb/db",
"Destination": "/data/db",
"Mode": "rw",
"RW": true,
"Propagation": "rprivate"
}
],
the Source contains string "/mnt/hgfs/ubuntu" tell us: It shared folder!
