current:

• latest, ${SATYSFI_VERSION}: full opam env
• slim, ${SATYSFI_VERSION}-slim: no opam env
• nightly: nightly build without opam env
• opam-slim, ${SATYSFI_VERSION}-opam-slim: partial opam env

motivation:

• upgrade satyrographos too
• latests, slim, opam-slim, nightly 🤔 confusing

idea 1:

• latest, ${SATYSFI_VERSION}-satyrographos-${SATYROGRAPHOS_VERSION}: current opam-slim
  • for normal users. This image cares almost all usecases, I think.
• nightly: same as latest but HEAD
  • for HEAD junky
• ${SATYSFI_VERSION}: only satysfi binary
  • for users that do not need to satyrographos
• ocaml, ${SATYSFI_VERSION}-satyrographos-${SATYROGRAPHOS_VERSION}-ocaml-${OCAML_VERSION}: current latest
  • for satyrographos-snapshot user
