   1 Alpine Linux 3.7+
   2 =========================================================
   3
   4 For building Alpine Linux dev packages, we use docker.
   5
   6 Install docker 17.05 or later
   7 -----------------------------
   8
   9 Depending on your host, there are different ways of installing docker.  Refer
  10 to the documentation here for instructions on how to install a free version of
  11 docker: https://www.docker.com/community-edition
  12
  13 Pre-built packages and docker images
  14 ------------------------------------
  15
  16 The master branch of https://github.com/frrouting/frr.git has a
  17 continuous delivery of docker images to docker hub at:
  18 https://hub.docker.com/r/ajones17/frr/. These images have the frr packages
  19 in /pkgs/apk and have the frr package pre-installed.  To copy Alpine
  20 packages out of these images:
  21
  22 ::
  23
  24    id=`docker create ajones17/frr:latest`
  25    docker cp ${id}:/pkgs _some_directory_
  26    docker rm $id
  27
  28 To run the frr daemons (see below for how to configure them):
  29
  30 ::
  31
  32    docker run -it --rm --name frr ajones17/frr:latest
  33    docker exec -it frr /bin/sh
  34
  35 Work with sources
  36 -----------------
  37
  38 ::
  39
  40    git clone https://github.com/frrouting/frr.git frr
  41    cd frr
  42
  43 Build apk packages
  44 ------------------
  45
  46 ::
  47
  48    ./docker/alpine/build.sh
  49
  50 This will put the apk packages in:
  51
  52 ::
  53
  54    ./docker/pkgs/apk/x86_64/
  55
  56 Usage
  57 -----
  58
  59 To create a base image with the frr packages installed:
  60
  61 ::
  62
  63    docker build --rm -f docker/alpine/Dockerfile -t frr:latest .
  64
  65 Or, if you don't have a git checkout of the sources, you can build a base
  66 image directly off the github account:
  67
  68 ::
  69
  70    docker build --rm -f docker/alpine/Dockerfile -t frr:latest \
  71         https://github.com/frrouting/frr.git
  72
  73 And to run the image:
  74
  75 ::
  76
  77    docker run -it --rm --name frr frr:latest
  78
  79 In the default configuration, none of the frr daemons will  be running.
  80 To configure the daemons, exec into the container and edit the configuration
  81 files or mount a volume with configuration files into the container on
  82 startup.  To configure by hand:
  83
  84 ::
  85
  86    docker exec -it frr /bin/sh
  87    vi /etc/frr/daemons
  88    cp /etc/frr/zebra.conf.sample /etc/frr/zebra.conf
  89    vi /etc/frr/zebra.conf
  90    /etc/init.d/frr start
  91
  92 Or, to configure the daemons using /etc/frr from a host volume, put the
  93 config files in, say, ./docker/etc and bind mount that into the
  94 container:
  95
  96 ::
  97
  98    docker run -it --rm -v `pwd`/docker/etc:/etc/frr frr:latest
  99
 100 We can also build the base image directly from docker-compose, with a
 101 docker-compose.yml file like this one:
 102
 103 ::
 104
 105    version: '2.2'
 106
 107    services:
 108       frr:
 109          build:
 110             context: https://github.com/frrouting/frr.git
 111             dockerfile: docker/alpine/Dockerfile
