* [monorepo] consolidate clsi-lb host/ip env-vars Target env-var is CLSI_LB_HOST. Keep CLSI_LB_IP populated for a week. * [clsi] initial version of /convert/pdf-to-jpeg * [rails] use fake-secrets in CI and Codespaces * [rails] adapt tests for using clsi to convert PDFs to image * [rails] add rake task for comparing clsi conversion with transloadit * [clsi] double check that output.jpg is a regular file Co-authored-by: Brian Gough <brian.gough@overleaf.com> * [clsi] fix composing basename * [monorepo] fix clsi-lb host env-var post merge * [monorepo] sort dev-environment.env hosts * [rails] use local pdf file rather than downloading it again Download from the old renderer code path still. It's dead code. * [terraform] clsi: enable pdf to jpg conversion --------- Co-authored-by: Brian Gough <brian.gough@overleaf.com> GitOrigin-RevId: 5ecaa8559d299486340bb3961f06b29f7c4dfcca
