How to find volumes that can be mounted in a docker container
DockerYou can find what can be mounted by inspected the container.
sudo docker container inspect my-container
This will give you a json output (much longer than this output)
{
"Id": "47eca95e3dfa40eac6fd6c2c03fec8cfb45d813a8e0af684de60d5292978e172",
"Created": "2018-11-24T15:56:47.673723654Z",
"Path": "docker-entrypoint.sh",
"Args": [
"redis-server"
],
"State": { },
"Config": {
"ExposedPorts": {
"6379/tcp": {}
},
"Volumes": {
"/data": {}
}
}
}
You can access easily with jq
like this :
sudo docker container inspect my-redis | jq '.[0].Config.Volumes'
This will give you the following output :
{
"/data": {}
}
The result of the mounted volume will be shown with the following :
sudo docker container inspect my-redis | jq '.[0].Mounts'
Output :
