environment variables

[rdilipk]

What's the correct way to read values from environment variables and construct a DSN at runtime for a sql_insert output processor? Or must some external bootstrapper-like program create the benthos config.yaml with these values before benthos can be started? IOW, I am wondering if this can be done from inside the config yaml itself.

I think GitHub must've skipped some notification emails... If we're slow to reply here, please reach out via the other means.

Regarding your question, please look at https://www.benthos.dev/docs/configuration/interpolation/. If you configure dsn: ${FOO}, then Benthos will attempt to set the dsn to the contents of the FOO environment variable. You can even specify a default value like so: dsn: ${FOO:foouser:foopassword@tcp(localhost:3306)/foodb} if you don't want to get an empty string when FOO isn't set.

I figured this one out myself. I completely missed the alternate contact mechanisms. Will keep them in mind next time. Thanks!
