Docker error:port is already allocated

• Docker Error

I encountered it when I tried to

$ docker-compose up -d --build

ERROR: 

for docker-compose_jupyternotebook_sql_adminer_1  Cannot start service adminer: driver failed programming external coCreating docker-compose_jupyternotebook_sql_db_1      ... error

d1220a2d3): Bind for 0.0.0.0:8080 failed: port is already allocated

 

• Cause

The port what I tried is already allocated to somewhere so it is unavailable to docker-compose up.

 

• Solution

First of all, check which container is using the port what I want to.

$ docker ps

And then kill it.

Stopping sql_adminer_1 ... done
Stopping sql_db_1      ... done

And then try to docker-compose up. And boom!
