Can't get Docker to run

[nealhead]

I've tried getting this running with Docker compose as well as with an image that someone else had made (bongobananne75), but I can't for the life of me get it to run. Initially I was getting this error:

panic: failed to get config from env: failed to create config file: data.txt: open data.txt: permission denied

goroutine 1 [running]:
main.main()
        /app/bin/memogram/main.go:13 +0x3d

Okay.. I never saw anything about a data.txt but I created a volume and mounted it to /app/data.txt but the file is empty as I have no idea what to put in it. So now I am receiving:

panic: failed to create bot: error call getMe, not found, Not Found

goroutine 1 [running]:
main.main()
        /app/bin/memogram/main.go:13 +0x3d

Any ideas would be appreciated...

I think those two issues are unrelated. The issue you're seeing occurs when no bot token is provided. You can quick-fix your data.txt problem multiple ways. Mount it:

docker run --rm --name memogram \
    -e SERVER_ADDR=dns:<my-server> \
    -e BOT_TOKEN=<my-token> \
    -v $(pwd)/data.txt:/app/data.txt \ <-- fix
    memogram

Run with a user that has privileges to modify /app:

docker run --rm --name memogram \
    -e SERVER_ADDR=dns:<my-server> \
    -e BOT_TOKEN=<my-token> \
    --user root \ <-- fix
    memogram

The cleanest fix, however, is to run the container with a non-root user that has privileges to write to /app. You can verify that this works by running twaslowski/memogram:stable, which runs with user 65532. The changes are available in #142.
