below is a tight patch that:

  • stops using sed
  • constructs a percent-encoded SMTP_URL
  • edits containers/app.yml via Ruby’s YAML (Psych), so YAML quoting/escaping is handled by a real parser
  • deletes the per-key SMTP vars to avoid contradictions

apply with git apply -p0 in the discourse_docker repo.

   ## If you cannot use SMTP_URL, you may set per-key variables instead.
   ## Beware that editing those lines with shell tools can be fragile if values include
   ## characters like @, :, /, ", \, or newlines.

why this works (and what it avoids)

  • bash layer: we only interpolate simple variables; secrets are passed into Python/Ruby via stdin/argv, not through sed regexes or shell evals.
  • sed layer: removed entirely.
  • YAML layer: Ruby/Psych handles quoting and escaping properly; no hand-rolled quoting.
  • SMTP creds: %-encoding in SMTP_URL is the right place to encode special characters for auth.

if you prefer to keep per-key vars, I can give you a sister patch that uses the same Ruby-YAML approach to set DISCOURSE_SMTP_* directly (still no sed), but the SMTP_URL route is the cleanest because it’s one key, one write, one encoding step.
