1454539 - ./mach taskcluster-build-image errors with missing argument: DOCKER_IMAGE_PARENT

Status: NEW

(Firefox Build System :: Task Configuration, task)

Description

[Tom Ritter [:tjr] (OOTO until 4/30 at least)]

My goal is to create a docker image that matches the TC environment as closely as possible, so I can build clang, and then use clang to build Firefox in as clean an environment as I can make.

It seems like I want either debian7-build or debian7-amd64-build.  However only debian7-build has a present Dockerfile.

taskcluster-load-image gives a similar error.

Comment 2

[Mike Hommey [:glandium]]

Presently, you need to define some things via environment variables. For debian7-build, you need to define DOCKER_IMAGE_PARENT, DOCKER_IMAGE_PACKAGES and ARCH. On automation, those are derived from taskcluster/ci/docker-image/kind.yml.

It looks like DOCKER_IMAGE_PACKAGES is a context hash or a taskid[0]; which doesn't seem easy/feasible to actually figure out or set myself.  I also don't know of a way to search treeherder for a job (only filter) to try and figure out the last values for these.
