Building bitcoin with a gitian-builder Docker container
This image allows automated gitian builds of bitcoin 0.9.1 using a docker container. Before proceeding make sure you have created the necessary wheezy and gitian-host images, see these instructions.
Afterwards you can create this image by running this script.
NOTE: this image currently supports only building of bitcoin 0.9.1, but it can be easily adapted to build other versions.
Preparing the gitian environment
If you have already prepared the base VMs (./build-base-vms.sh) inside the gitian host container, all what you need to do is:
ssh -o SendEnv= debian@your-gitian-host ./build-bitcoin.sh
build-bitcoin.sh is a script that will download & build all the dependencies and then bitcoin itself, for both i386 and amd64 Linux architectures.
NOTE: the SendEnv= is there to overcome an issue in gitian-builder that allows pollution of the LXC environment.
Signing
Now you have completed the build of bitcoin and only the signing part is left. Before doing that, you can verify if signatures are matching with those of other developers by peeking inside ~/gitian.sigs of the running container.
In order to sign you have to either put your private key in the container's ~/.gnupg or perform the signing externally, at your option.
If you have the private key in the container (also displayed by gpg -K), then you can use this script:
#!/bin/bash
set -e
export SIGNER=yourSignerName
export VERSION=0.9.1
cd gitian-builder
./bin/gsign --signer $SIGNER --release ${VERSION} --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-linux.yml
Submitting your signature
If everything went well, you can fork the gitian sigs repo, commit your signatures and submit a pull request for inclusion.
