fix Docker user on arm Use simple USER directive. Using `addgroup` in final `arm` image when building on amd64 doesn't work. I must have made a mistake during cross build verification. Alternative is to use qemu-static but it's not worth it for this. 2019-05-03 06:38:03 +00:00			`USER 2000:2000`
Potentially breaking change: docker user & group Run as non-root user and group In the unlikely event that you are currently persisting data to disk then this change may break file read/write access due to a change in the UID/GID that the oauth2_proxy process runs as. Run as non-root system user and group `oauth2proxy` with UID/GID `2000` to avoid clashing with typical local users. An alternative to creating a separate user is to ~~chown binary and~~ run as `USER nobody`, which also works, can amend this PR if required. Least access privileges.
