Hello all. I’ve got a weird error when running `docker-compose up --abort-on-container-exit`. Seems like some dependencies aren’t compatible or something. Could someone please explain what’s going on and maybe suggest a fix? ![05](https://files.chunter.kodeco.com/original/3X/e/3/e3a94866c169c5148c4ae9222c778ef35e8409ff.jpeg) ---

@thedan84 have you updated the Swift version in the Dockerfiles? Could you post the docker file? 5.1 removed OpenSSL so you’d need to add that back in ---

@0xtim Here are the contents of the Dockerfile: ``` FROM swift:5.1 WORKDIR /package COPY . ./ RUN swift package resolve RUN swift package clean CMD ["swift", "test"] ``` Yes, I have updated the Swift version in the Docker file, should I go back to 4.2 to make it work? Or just add OpenSSL to my Swift Package? ---

I managed to get rid of the errors by changing the Swift version to 4.2. But now it fails because the Google and/or GitHub callback URLs aren’t set, although I’ve added them to the Environment variables. The tests succeed in Xcode, but I guess because the Xcode project is discarded when running the app in Linux the variables aren’t accessible anymore? ---

@thedan84 yeah you don’t have any access to the Xcode set environment variables inside Docker. One way I get around it is to hard code some test environment variables when you’re running tests (by looking to see if `env == .testing`). You can pass environment variables to your container with `-e GOOGLE_CALLBACK_URL=http://localhost:8080/` when doing `docker run` For the language stuff - you can use `FROM swift 5.1.1` you just need to add [these lines](https://github.com/vapor/api-template/blob/master/web.Dockerfile#L8-L10) before you do any building ---

@0xtim Thanks a lot for the hints. Will try it out.
