By default, container ports are not accessible outside of Docker. Other containers can work with them, but you can’t access them from your host.
$ fin ps
Name Command State Ports
--------------------------------------------------------------------------
netscout_cli_1 /opt/startup.sh gosu root ... Up 22/tcp, 9000/tcp
netscout_db_1 /entrypoint.sh mysqld Up 3306/tcp
netscout_web_1 /opt/startup.sh apache2 -D ... Up 443/tcp, 80/tcp
The container ports in the right column are exposed to Docker. Follow the steps below to expose any of these ports to the host.
1. Create docksal-local.yml.
This is recommended for creating local overrides instead of modifying docksal.yml directly.
2. Put the following contents into docksal-local.yml.
This will instruct Docker to export port 22 of the cli service as port 2222 on your host.
version: "2.1"
services:
cli:
ports:
- "2222:22"
Note the quotes. Yaml interprets some numbers with a colon as base64 numbers, so you need quotes here.
3. Run fin project start to apply the new configuration.
4. Confirm that your port is exposed.
Note: 0.0.0.0:2222 is pointing to 22.
$ fin ps
Name Command State Ports
---------------------------------------------------------------------------------
netscout_cli_1 /opt/startup.sh gosu root ... Up 0.0.0.0:2222->22/tcp, 9000/tcp
netscout_db_1 /entrypoint.sh mysqld Up 3306/tcp
netscout_web_1 /opt/startup.sh apache2 -D ... Up 443/tcp, 80/tcp
5. Accessing exposed port
To access the exposed port use dedicated Docksal IP 192.168.64.100, not localhost.
I.e. in the example above access 192.168.64.100:2222.
