viv

In a Dockerfile

To build a vendor/ stage without a PHP runtime, use the published image in place of composer:2:

FROM ghcr.io/svandragt/vivace:0 AS vendor
COPY composer.json composer.lock ./
RUN ["viv", "install", "--no-dev"]

FROM php:8.4-fpm
COPY --from=vendor /app/vendor /app/vendor

Two things differ from the composer:2 stage it replaces:

  • Write RUN in exec form, as above. The image has no shell, so the familiar RUN viv install --no-dev does not work.
  • The image runs viv by default and ships the composer shim beside it, so RUN ["composer", "install", "--no-dev"] works too if you would rather not edit the command.
  • The image carries no real Composer to fall back to, so a command or flag the shim doesn't understand hard-errors there instead of silently running Composer, the way it would on a machine that still has Composer installed. composer --version still works: it prints the shim's own version.

Tags are :0.21, :0.21.0 and :0. There is no :latest: a moving tag that silently resolves to nothing breaks scripted installs, which is the mistake that kept releases/latest returning 404 for ten releases.
