  • phpunit.xml groups let CI split the suite

    Note2 min read

    A suite that takes twenty minutes gets run less often, which is the opposite of what it is for. Groups let the fast tests gate every push and…

  • A deploy that is nothing but a symlink swap

    Note2 min read

    Copying files into the live directory means the site serves a half-updated tree for the duration — new templates against old classes, for as long as the copy…

  • composer validate belongs in CI

    Note1 min read

    A composer.json edited by hand and a lock file regenerated on a different machine drift apart quietly, and the first symptom is usually a deploy installing something nobody…

  • A deployment pipeline that runs the tests first

    Deep dive15 min read

    Deploying by rsync on a Friday afternoon, and what replaced it: lint, test, build, stage, promote — with a rollback that is the same mechanism rather than a…

  • Docker for Mac replaced the virtual machine

    Deep dive8 min read

    The shared-folder problem that nearly killed this last year is gone. What changes in the compose file, what the new file sharing costs, and where Linux and Mac…

  • The CI box gets its own deploy key, and it is read-only

    Note1 min read

    Giving CI a copy of a developer’s key, or an account with write access, means a compromised build server can push to the repository — and a build…

  • Certificates that renew themselves

    Deep dive9 min read

    Free certificates went GA this month. Automating issuance and renewal, the rate limits that catch staging first, and the monitoring that has to outlive the automation.

  • Two images instead of the multi-stage build you cannot have yet

    Note2 min read

    Building assets inside the runtime image drags Node, the whole node_modules tree and a compiler toolchain into production — several hundred megabytes to produce one bundle. There is…

  • A smoke test is not an integration test

    Note1 min read

    Both hit a running system, so they get put in the same suite and run at the same time. They answer different questions and should fail at different…

  • A first serious attempt at Docker for local development

    Deep dive15 min read

    Two days lost to PHP extension mismatches. A container per service, what the shared-folder performance problem costs on a VM, and whether it was worth it.
