1 [Dockerfiles][] for assorted [Gentoo][]-based [Docker][] images.
3 Dockerfiles are sorted into directories with names matching the
4 suggested repository. To avoid duplicating ephemeral data (namespace,
5 timestamp tag, …), they appear in the `Dockerfile.template` as markers
6 (`NAMESPACE`, `TAG`, …). The `build.sh` script replaces the markers
7 with values while generating a `Dockerfile` from each
8 `Dockerfile.template`, and then builds each tag with:
10 $ docker build -t $NAMESPACE/$REPO:$TAG $REPO
14 $ docker build -t wking/gentoo-en-us:20131205 gentoo-en-us
16 The dependency graph is:
18 wking/gentoo (amd64 stage3)
19 `-- gentoo-portage (adds portage directory)
20 `-- gentoo-en-us (adds locale)
21 `-- gentoo-syslog (adds syslog-ng and associates)
22 |-- buildbot (adds a Buildbot master and slave)
23 |-- postgresql (adds PostgreSQL)
24 `-- redis (adds Redis)
30 to seed from the Gentoo mirrors and build all images. There are a
31 number of variables in the `build.sh` script that configure the build
32 (`AUTHOR`, `NAMESPACE`, …). We use [POSIX parameter
33 expansion][parameter-expansion] to make it easy to override variables
36 $ NAMESPACE=jdoe DATE=20131210 ./build.sh
38 I'd like to avoid bloating the images with the Portage tree, but
39 without ugly hacks [that is not currently possible][3156] is mounted
