The following script is for use with Zimbra's GitHub repository: https://github.com/zimbra/zm-build
Builds created with this build script can be found on my website here if you want to save yourself the hassle of building yourself! Builds on the website will be updated quarterly.
The script created here are based on the zm-build documentation, and are to help make things much easier for you. The script automatically detect your distribution, installs dependencies, and builds Zimbra without you having to do anything else manually. So far it supports the distributions below:
There is also a pre-configured config.build which will build Zimbra 9.0.0 OSE/FOSS
For future Zimbra 9.x releases, all that will be required is to adapt the contents of config.build with the appropriate version numbers - or download a particular release here:
BUILD_NO = 0001
BUILD_RELEASE = KEPLER
BUILD_RELEASE_NO = 9.0.0
BUILD_RELEASE_CANDIDATE = GA
BUILD_TYPE = FOSS
BUILD_THIRDPARTY_SERVER = files.zimbra.com
INTERACTIVE = 0the information that you likely will want to change is BUILD_NO, BUILD_RELEASE, BUILD_RELEASE_NO. The remaining values shouldn't need to be changed.
If you have any issues/problems when using the script, please open an issue so that I can help resolve it.
I have tested with all versions supported by this script, and successfully built Zimbra.
The build server will need at least 4GB ram. Previously it was possible to build on 2GB, but this now fails for some of the java packages with an error: error starting modern compiler. Therefore if you see this error, increase the memory of the build server.
You will need a GitHub account, as the Zimbra build process needs to connect to GitHub via SSH. Therefore, you will need to generate an SSH key if you don't have one, and then upload the contents of id_rsa.pub here: https://github.com/settings/keys
Please do not attempt to build Zimbra without completing this step, as it simply won't work.
You can create a key by doing this:
ssh-keygen -t rsa -b 4096 -C "your_email@address"the email address needs to be the one used for your GitHub account.
Make sure that there are no other versions of JRE/JDK installed on your build server as these will conflict with openjdk-8 which Zimbra uses. For example on Ubuntu 18.04 by default some OpenJDK-11 packages are installed, so these needs to be removed prior to building.
Now clone this repository:
git clone https://github.com/ianw1974/zimbra-build-scripts
cd zimbra-build-scriptsnow you can run the script.
A help parameter --help has been added to the script so you can reference it to find out what steps need to be done to build Zimbra. These saves you from having to reference this readme file. It summarises the steps required, to make sure that you have uploaded an SSH key to your GitHub profile, that any other version of Java has been removed from your system prior to installing dependencies and building Zimbra.
./zimbra-build-helper.sh --help
Zimbra Build Helper script!
Valid parameters are as follows:
--install-deps - Installs required dependencies
--build-zimbra - Builds Zimbra
--cleanup - Cleanup previously attempted builds
--help - Shows this help screen
At the beginning of the script these variables can be changed if you want:
MAINDIR=/home/git
PROJECTDIR=zimbra
Build summary step-by-step:
1. Generate ssh key: ssh-keygen -t rsa -b 4096 -C "your_email@address"
2. Upload this to your GitHub profile: https://github.com/settings/keys
3. Only OpenJDK 8 can be installed on the build server, remove other versions
4. Run:./zimbra-build-helper.sh --install-deps
5. Run:./zimbra-build-helper.sh --build-zimbraAlso, if you run the script without passing a parameter, it will display output asking you to use the --help parameter for more info to help you.
Install the dependencies by running:
./zimbra-build-helper.sh --install-depsthis will detect the distribution and version you are running, and run the appropriate commands to install the build dependencies.
First edit the config.build if necessary as this will build 9.0.0 by default. This will ensure you are building for the version you want.
By default, it will create and build under /home/git/zimbra and everything related to the build will be located here. This ensures your system stays tidy during the build process (everything will be placed under /home/git/zimbra - about 59+ directories). If you really want to build it somewhere else then edit the script and change the variables as seen below:
# Variables
MAINDIR=/home/git
PROJECTDIR=zimbraonly change these if you really, really need to, otherwise the build process might fail if the two values above are incorrectly supplied, or you put on a partition that doesn't have enough disk space to build Zimbra. Zimbra needs approximately 5GB of available space to build successfully.
Please note, if you pull my repository in the future, or when downloading a new release, these changes will be lost. So if you use a custom location/settings to build other than what I have by default, you will need to change this each time you pull/download.
Once you have done all the changes you need, build Zimbra by running:
./zimbra-build-helper.sh --build-zimbraDepending on the CPU/RAM available on your build server, the build process could take approximately 1 hour, maybe less. I built on a server with 4cpu and 8GB of memory in 45 minutes. This was on a virtual server under OpenStack though, so your mileage may vary.
The script will automatically clone https://github.com/zimbra/zm-build so you don't need to do this. Then the script patches zimbra/zm-build/instructions/bundling-scripts/zimbra-store.sh because of a failure for non-existant directory convertd. This may not be needed in the future if Synacor fix their build script. The patch fixes the script to create it before building.
After the patch has been applied, it builds Zimbra.
At the end, you will find the created Zimbra archive file under /home/git/zimbra/BUILDS/UBUNTU20_64-KEPLER-900-20201013092939-FOSS-0001/zcs-9.0.0_GA_1.UBUNTU20_64.20201013092939.tgz if building for Ubuntu 20.04. The directory name and archive file name will vary if building for different distributions.
You can then unpack this archive file and install/upgrade Zimbra in the usual manner.
A Dockerfile is provided to build the builder image, which can later be used to create a release.
The default Dockerfile builds an image for Ubuntu 20.04. To build for other distributions, edit the Dockerfile and comment/uncomment the version you wish to build for. An example is shown below:
# Uncomment the distro that you wish to build for
#ARG RELEASE=almalinux:8.9
#ARG RELEASE=oraclelinux:8.9
#ARG RELEASE=rockylinux:8.9
ARG RELEASE=ubuntu:20.04for example to build for Rocky Linux 8.6 we comment the Ubuntu line, and uncomment the Rocky Linux line, so it looks like this:
# Uncomment the distro that you wish to build for
#ARG RELEASE=almalinux:8.9
#ARG RELEASE=oraclelinux:8.9
ARG RELEASE=rockylinux:8.9
#ARG RELEASE=ubuntu:20.04Build support for CentOS is excluded due to it effectively being EOL. RHEL is excluded due to requiring subscriptions for enabling repositories - this makes things difficult for the build process. It may be offered in the future. Ubuntu 16.04 and 18.04 are excluded due to it being EOL.
Just like when building normally, an SSH key is required to be uploaded to your account. With the docker/podman commands, we are mounting the /root/.ssh directory to the docker/podman container - therefore you have to make sure that your SSH key has been generated, uploaded to your GitHub account and placed within this directory. If not, then the build process within docker/podman will fail. Follow the steps in the Preparation section at the beginning of this README.
To build the image (replace docker with podman if using the latter):
docker build -t zbs .Now we can build Zimbra:
docker run --rm -v zbs:/home/git/zimbra/BUILDS -v /root/.ssh:/root/.ssh zbsThere are two bind mounts: one for the build output and one for the ~/.ssh directory containing the key to access GitHub repos. Since you are most likely using docker/podman as root, the path above should be fine. Adapt where necessary. For docker, using the above command will create the volume /var/lib/docker/volumes/zbs and the builds can be found here later.
Once the volume and build image is no longer needed, they can be removed:
docker volume rm zbs
docker image rm zbsPlease note I cannot be held responsible for misuse of this script or any adverse affects on your system. The script is provided as-is.
