Maybe features?

• HTTP API for starting/stopping services
• Service dependencies (A depends on B)

Building

1. Run gcc -shared -fPIC src/stub.c -o libstub.so
2. Run cargo build
3. Profit!

Service definition

In eva.ini:

[SERVICE_NAME]
exec=/path/to/executable
env_foo=value
keepalive=true
...

Forwarding environment variables

You have two options:

1. Run EVA__SERVICE_NAME__VAR__=VAL ./eva
2. Set env__VAR=VAL in eva.ini

Note that (1) overrides (2).

Todo

• Also store PID (look at procinfo)
• Live process memory usage, etc.
• Email alerts (SendGrid, MailChimp, ... ?)
