h1. All-in-one package (draft / work in progress, see #16306 and "arvados-server boot (google doc)":https://docs.google.com/document/d/1UvABO9WOg5svK2LIETaEgg9jZQp6Lydb47HrG3NMsFM/edit) "arvados-server-easy" is a debian/rpm package that can be used to create a single-node production cluster from scratch with minimal effort: <pre> apt-get install arvados-server-easy arvados-server init -cluster-id x1234 systemctl start arvados </pre> This page is mostly about how we build/maintain the package, rather than how to use it. h2. Building source:cmd/arvados-dev (similar to arvados-client/server) has: * a "buildpackage" subcommand that creates a deb/rpm package from source (i.e., a checkout of the arvados source tree, possibly with local modifications). It takes care of installing dependencies, fpm, etc. * "docker-build-install", a bash script (could move to Go) that builds a package for a given OS version by injecting the buildpackage command into a docker container with that OS version, installs the resulting package into a new base OS image, and saves the resulting image for testing purposes. (currently, debian:10 is implemented) * "docker-boot", a bash script (could move to Go) that brings up a cluster using the testing image (the one with arvados-server-easy already installed), optionally injecting local changes to enable a quicker dev cycle. For example, "docker-boot.sh cmd/arvados-server" builds a new arvados-server binary on the host, then starts a container using the test image but with the new arvados-server binary bind-mounted over the packaged one. Package publishing outline (pseudocode): <pre> ./cmd/arvados-dev/docker-build-install.sh -os debian:10 -force-buildimage -force-installimage </pre> Development cycle, when working on Go programs and other things that docker-boot.sh knows how to rebuild+overlay: cycle: <pre> ./cmd/arvados-dev/docker-build-install.sh -os debian:10 # (just once, takes 10+ minutes minutes) ./cmd/arvados-dev/docker-boot.sh # (edit some Go code locally) ./cmd/arvados-dev/docker-boot.sh cmd/arvados-server # takes 15+ seconds to start 15 seconds, mostly starting postgresql, create creating db, etc., and boot etc # (edit some Go code locally) ./cmd/arvados-dev/docker-boot.sh cmd/arvados-server nginx.conf # ... </pre> Development cycle when working on packaging stuff itself: * Rebuild the package-building image from base OS image, then use it to build a new package (this is slow because it downloads/installs OS package dependencies, compiles Ruby, etc.): <pre>./cmd/arvados-dev/docker-build-install.sh -os debian:10 -force-buildimage</pre> * Build a new package, then install it onto a base OS image (this checks whether the package still installs & boots correctly after you change the OS dependencies in source:lib/install, or after the base OS itself has changed): <pre>./cmd/arvados-dev/docker-build-install.sh -os debian:10 -force-installimage</pre> * Build a new package, and reinstall it on the existing cached installimage (this builds and tests an actual package, but skips re-downloading/re-installing all of its OS dependencies): <pre>./cmd/arvados-dev/docker-build-install.sh -os debian:10</pre>
