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
7 markers with values while generating a `Dockerfile` from each
8 `Dockerfile.template` (using [envsubst][]), and then builds each tag
11 $ docker build -t $NAMESPACE/$REPO:$TAG $REPO
15 $ docker build -t wking/gentoo-en-us:20131205 gentoo-en-us
17 The dependency graph is:
19 wking/gentoo (amd64 stage3)
20 `-- gentoo-portage (adds portage directory)
21 `-- gentoo-en-us (adds locale)
22 `-- gentoo-syslog (adds syslog-ng and associates)
23 |-- buildbot (adds a Buildbot master and slave)
24 |-- docker-registry (adds a Docker registry server)
25 |-- gentoo-layman (adds layman for Gentoo overlays)
26 | `-- package-cache (adds a package-cache proxy)
27 |-- memcached (adds Memcached)
28 |-- nginx (adds Nginx)
29 | |-- nginx-proxy (SSL/TLS proxying via SNI)
30 | |-- kibana (adds Kibana)
31 | `-- kibana-azure (adds Azure's Kibana)
32 |-- postgresql (adds PostgreSQL)
33 |-- redis (adds Redis)
34 |-- salt-minion (adds a Salt Stack minion)
35 |-- stunnel (adds stunnel)
36 `-- gentoo-java (adds IcedTea)
37 `-- elasticsearch (adds Elasticsearch)
43 to seed from the Gentoo mirrors and build all images. There are a
44 number of variables in the `build.sh` script that configure the build
45 (`AUTHOR`, `NAMESPACE`, …). We use [POSIX parameter
46 expansion][parameter-expansion] to make it easy to override variables
49 $ NAMESPACE=jdoe DATE=20131210 ./build.sh
51 I'd like to avoid bloating the images with the Portage tree, but
52 without ugly hacks [that is not currently possible][3156].
