Add simple script for running gitian-build
This shell script creates a docker image for running the gitian-build.py script, to avoid version incompatibilities. The builds may be signed automatically after manually reviewing the build hashes. Only docker.io and apt-cacher-ng are required to be installed on the host. The MacOSX SDK should also be present in this directory if Mac builds are desired. A container named "gitrun" is used to launch the builds, and all output will reside in this container as well.

Quick Gitian building with docker
|
||||
=================================
|
||||
|
||||
*Setup instructions for a Gitian build of Monero using Docker.*
|
||||
|
||||
Gitian supports other container mechanisms too but if you have a Debian or
|
||||
Ubuntu-based host the steps can be greatly simplified.
|
||||
|
||||
Preparing the Gitian builder host
|
||||
---------------------------------
|
||||
|
||||
The procedure here will create a docker container for build preparation, as well as
|
||||
for actually running the builds. The only items you must install on your own host
|
||||
are docker and apt-cacher-ng. With docker installed, you should also give yourself
|
||||
permission to use docker by adding yourself to the docker group.
|
||||
|
||||
```bash
|
||||
sudo apt-get install docker.io apt-cacher-ng
|
||||
sudo usermod -aG docker $USER
|
||||
su $USER
|
||||
```
|
||||
|
||||
The final `su` command is needed to start a new shell with your new group membership,
|
||||
since the `usermod` command doesn't affect any existing sessions.
|
||||
|
||||
If you want Mac binaries included in your build, you need to obtain the MacOS SDK:
|
||||
|
||||
```bash
|
||||
curl -O https://bitcoincore.org/depends-sources/sdks/MacOSX10.11.sdk.tar.gz
|
||||
```
|
||||
|
||||
Other User Preparation
|
||||
----------------------
|
||||
|
||||
The final step will be to `gpg` sign the results of your build and upload them to GitHub.
|
||||
Before you can do that, you'll need
|
||||
* a GitHub account.
|
||||
If your GitHub account name is different from your local account name, you must
|
||||
set your GitHub account name for the script to use:
|
||||
|
||||
```bash
|
||||
export GH_USER=<github account name>
|
||||
```
|
||||
|
||||
* PGP keys - if you don't have one already, you can use `gpg --quick-gen-key` to generate it.
|
||||
* a fork of the [gitian.sigs](https://github.com/monero-project/gitian.sigs/) repo on your GitHub account.
|
||||
Please follow the directions there for uploading your key first.
|
||||
|
||||
**Note:** Please ensure your gpg public key is available to check signatures by adding it to the [gitian.sigs/gitian-pubkeys/](https://github.com/monero-project/gitian.sigs/tree/master/gitian-pubkeys) directory in a pull request.
|
||||
|
||||
|
||||
Building the Binaries
|
||||
---------------------
|
||||
|
||||
The dockrun.sh script will do everything to build the binaries. Just specify the
|
||||
version to build as its only argument, e.g.
|
||||
|
||||
```bash
|
||||
./dockrun.sh v0.17.2.3
|
||||
```
|
||||
|
||||
The build should run to completion with no errors, and will display the SHA256 checksums
|
||||
of the resulting binaries. You'll be prompted to check if the sums look good, and if so
|
||||
then the results will be signed, and the signatures will be pushed to GitHub.
|
||||
|
||||
You can also look in the [gitian.sigs](https://github.com/monero-project/gitian.sigs/) repo and / or [getmonero.org release checksums](https://web.getmonero.org/downloads/hashes.txt) to see if others got the same checksum for the same version tag. If there is ever a mismatch -- **STOP! Something is wrong**. Contact others on IRC / GitHub to figure out what is going on.
|
||||
|
||||
|
||||
Other Options
|
||||
-------------
|
||||
|
||||
This script just runs the [gitian-build.py](gitian-build.py) inside a container named `gitrun`.
|
||||
You can set other options for that script by setting the OPT variable when running `dockrun.sh`
|
||||
e.g.
|
||||
|
||||
```bash
|
||||
OPT="-j 8" ./dockrun.sh v0.17.2.3
|
||||
```
|
||||
|
||||
You can also examine the build and install logs by running a shell in the container, e.g.
|
||||
|
||||
```bash
|
||||
docker exec -it gitrun /bin/bash
|
||||
more builder/var/install-linux.log
|
||||
```
|
||||

|
|||
|
||||
* Gitian gives you the option of using any of 3 different virtualization tools: `kvm`, `docker` or `lxc`. This documentation will only show how to build with `lxc` and `docker` (documentation for `kvm` is welcome). Building with `lxc` is the default, but is more complicated, so we recommend docker your first time.
|
||||
|
||||
* For a shortcut using `docker` follow the instructions in [DOCKRUN.md](DOCKRUN.md) instead
|
||||
of following the rest of this document..
