[hotfix] inject .env file into signald container
fixes the following bug in !335 (merged) in a way designed to prevent similar easy-to-make mistakes from recurring..
- SYMPTOM: shipped new data dog instrumentation in signald entrypoint that should only run in prod, but it did not run in prod
- CAUSE: the
SIGNALBOOST_ENVRIONMENT
env var being inspected for whether or not we were in prod was not set b/c it is defined in.env
which is not available to the signald container - FIX: inject
.env
and.env.dev
into the prod and dev signald containers (respectively) so that this bug won't happen and future devs may safely assume that any env vars defined in env file are available in signald container
