According to instructions [here](http://docs.metasfresh.org/installation_collection/EN/How_do_I_change_the_webui_ports_for_metasfresh_docker) about changing ports, I have modified ports as following,

```auto
webui:
  build: webui
  links:
    - webapi:webapi
  ports:
    - "8080:80"
    - "8443:443"
  restart: always
  volumes:
    - /etc/localtime:/etc/localtime:ro
    - /etc/timezone:/etc/timezone:ro
  #uncomment and set to URL where metasfresh will be available from browsers
  #environment:
    - WEBAPI_URL=https://my.domain.com:8443

```

but it results in the below error,

```auto
Creating metasfresh_webui_1 ... error

ERROR: for metasfresh_webui_1 Cannot create container for service webui: b'invalid mode: 8443'

ERROR: for webui Cannot create container for service webui: b'invalid mode: 8443'
ERROR: Encountered errors while bringing up the project.

```

trying to build for standard TLS port 443 `https://my.domain.com` results in the below error,

```auto
Creating metasfresh_webui_1 ... error

ERROR: for metasfresh_webui_1 Cannot create container for service webui: b'create WEBAPI_URL=https: "WEBAPI_URL=https" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path'

ERROR: for webui Cannot create container for service webui: b'create WEBAPI_URL=https: "WEBAPI_URL=https" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path'
ERROR: Encountered errors while bringing up the project.

```

I’m looking for running metasfresh-docker on custom port `8443` behind caddy server; so that, external requests to `https://my.domain.com` to be directed by caddy to `https://my.domain.com:8443` internally.

Please advise, Thanks.

Hi @OnlineAlone

Looks like you forgot to uncomment `environment:` since it’s a new “section”.  
If it’s not uncommented, docker-compose thinks it belongs to the section above `volumes:` - that’s why you get this weird error.

It should look like this:

```auto
...
  restart: always
  volumes:
    - /etc/localtime:/etc/localtime:ro
    - /etc/timezone:/etc/timezone:ro
  #uncomment and set to URL where metasfresh will be available from browsers
  environment:
    - WEBAPI_URL=https://my.domain.com:8443

```

(beware indentations)

Cheers.

Thanks @julian.bischof

On other note, please advise on changing `WEBAPI_URL` later on after getting the platform running.  
I want to deploy it on VPS using IP address before I get it pointed by URL with TLS certificate.

Cheers,

metasfresh is installed by docker and waited long till the database being populated but still showing the blank page as below,

 ![metasfresh](https://forum.metasfresh.org/uploads/default/original/1X/6cdbf38a943e674bb28bdd9e349950c34b900580.png)

```auto
webui:
  build: webui
  links:
    - webapi:webapi
  ports:
    - "8080:80"
    - "8443:443"
  restart: always
  volumes:
    - /etc/localtime:/etc/localtime:ro
    - /etc/timezone:/etc/timezone:ro
  #uncomment and set to URL where metasfresh will be available from browsers
  #environment:
    #- WEBAPI_URL=http://example.com:8080

```

`WEBAPI_URL` entry were left commented (as it is) to allow access by IP address for now and only port 8080 is working while port 8443 doesn’t respond.

Please advise, Thanks
