Building the Containers

Build From Source

There are many cases where you may want to build the containers from source, such as working on a patch to contribute a feature. This guide provides the instructions to get you set up to build from source.

Requirements

CentOS 7 or Red Hat 7 environment. The instructions below are set up for CentOS 7, but you can read the installation guide for additional instructions
go version 1.13+
buildah 1.14.9+
git

Setup

On your system, be sure you have installed the requirements. You can do so with the following commands:

sudo yum -y install epel-release
sudo yum -y install golang git buildah

Create a fork of the Crunchy Container Suite repository and clone it to the environment using the following commands below:

mkdir -p $HOME/cdev/src/github.com/crunchydata $HOME/cdev/pkg $HOME/cdev/bin
cd $HOME/cdev/src/github.com/crunchydata
git clone https://github.com/crunchydata/crunchy-containers
cd crunchy-containers

Set up your local environmental variables to reference the containers you want to build. For instance, to build the latest version, you would use the following variables:

export GOPATH=$HOME/cdev        # set path to your new Go workspace
export GOBIN=$GOPATH/bin        # set bin path
export PATH=$PATH:$GOBIN        # add Go bin path to your overall path
export CCP_BASEOS=ubi8       # centos7 for CentOS, ubi8 for Red Hat Universal Base Image
export CCP_PGVERSION=13        # The PostgreSQL major version
export CCP_PG_FULLVERSION=13.7
export CCP_POSTGIS_VERSION=3.0
export CCP_VERSION=4.6.7
export CCP_IMAGE_PREFIX=crunchydata # Prefix to put before all the container image names
export CCP_IMAGE_TAG=$CCP_BASEOS-$CCP_PG_FULLVERSION-$CCP_VERSION   # Used to tag the images
export CCP_POSTGIS_IMAGE_TAG=$CCP_BASEOS-$CCP_PG_FULLVERSION-$CCP_POSTGIS_VERSION-$CCP_VERSION # Used to tag images that include PostGIS
export CCPROOT=$GOPATH/src/github.com/crunchydata/crunchy-containers    # The base of the clone github repo

You can save these variables to be set each time you open up your shell by adding them to your .bashrc file:

cat >> ~/.bashrc <<-EOF
export GOPATH=$HOME/cdev
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
export CCP_BASEOS=ubi8
export CCP_PGVERSION=13
export CCP_PG_FULLVERSION=13.7
export CCP_POSTGIS_VERSION=3.0
export CCP_VERSION=4.6.7
export CCP_IMAGE_PREFIX=crunchydata
export CCP_IMAGE_TAG=$CCP_BASEOS-$CCP_PG_FULLVERSION-$CCP_VERSION
export CCP_POSTGIS_IMAGE_TAG=$CCP_BASEOS-$CCP_PG_FULLVERSION-$CCP_POSTGIS_VERSION-$CCP_VERSION
export CCPROOT=$GOPATH/src/github.com/crunchydata/crunchy-containers
EOF

Download the GPG Keys and repository files that are required to pull in the packages used to build the containers:

cd $CCPROOT
curl https://api.developers.crunchydata.com/downloads/repo/rpm-centos/postgresql12/crunchypg12.repo > conf/crunchypg12.repo
curl https://api.developers.crunchydata.com/downloads/repo/rpm-centos/postgresql11/crunchypg11.repo > conf/crunchypg11.repo
curl https://api.developers.crunchydata.com/downloads/gpg/RPM-GPG-KEY-crunchydata-dev > conf/RPM-GPG-KEY-crunchydata-dev

Run the setup script to download the remaining dependencies

cd $CCPROOT
make setup

Build

You can now build the containers:

cd $CCPROOT
make all

if you want to build an individual container such as crunchy-postgres, you need to reference the individual name:

cd $CCPROOT
make postgres

To learn how to build each container, please review the Makefile targets within the Makefile in the repository.
