About

This docker build file is created in order to build i2pd and include the i2pd-tools as well. The reason for doing this is that most involved i2p operations require the tools but they are not included inside the official i2pd Docker container such that compiling them outside of a container seems like overkill when they could just be bundled together.

Usage

Check out the bundle with Subversion to an empty directory: 

svn export --force https://svn.grimore.org/docker/build/i2pd/

change to that directory and issue: 

docker build -t TAG .

where:

After i2pd is built, a container can be created and ran either via docker run or deployed within the swarm with docker stack deploy.

Note that if the image is to be deployed to a swarm, then more than likely the image should be committed to a local registry serving the local docker swarm.

# 1. Building binary
#   Each RUN is a layer, adding the dependencies and building i2pd in one layer takes around 8-900Mb, so to keep the
#   image under 20mb we need to remove all the build dependencies in the same "RUN" / layer.
#
#   1. install deps, clone and build.
#   2. strip binaries.
#   3. Purge all dependencies and other unrelated packages, including build directory.
