Installing Shifter on a RHEL/Centos/Scientific Linux 7 System

Building RPMs

First, ensure your build system has all necessary packages installed:

yum install epel-release
yum install rpm-build gcc glibc-devel munge libcurl-devel json-c \
    json-c-devel pam-devel munge-devel libtool autoconf automake \
    gcc-c++ python-pip xfsprogs squashfs-tools python-devel

Next, if not using a prepared source tarball, generate one from the repo:

git clone https://github.com/NERSC/shifter.git
[[ perform any needed git operations to get a particular branch or commit
   you require.  We currently recommend the 16.08.3_2 tag. ]]
VERSION=$(grep Version: shifter/shifter.spec | awk '{print $2}')
cp -rp shifter "shifter-$VERSION"
tar cf "shifter-$VERSION.tar.gz" "shifter-$VERSION"

Build the RPMs from your tarball:

rpmbuild -tb "shifter-$VERSION.tar.gz"

Note about Slurm support To build with Slurm support do:

rpmbuild -tb "shifter-$VERSION.tar.gz" --define "with_slurm /usr"

Change “/usr” to the base path Slurm is installed in.

Installing the Image Manager

Install the Shifter runtime RPM

yum -y install shifter{,-imagegw}-1*rpm

Create a config, create directories, start Mongo.

cp /etc/shifter/imagemanager.json.example /etc/shifter/imagemanager.json mkdir /images mkdir -p /data/db mongod –smallfiles &

Start Munge

echo “abcdefghijklkmnopqrstuvwxyz0123456” > /etc/munge/munge.key chown munge.munge /etc/munge/munge.key chmod 600 /etc/munge/munge.key runuser -u munge munged

Start the image gateway and a worker for “mycluster”

gunicorn -b 0.0.0.0:5000 –backlog 2048 shifter_imagegw.api:app &

Installing the Runtime

yum -y install shifter{,-runtime}-1*rpm cp /etc/shifter/udiRoot.conf.example etc/shifter/udiRoot.conf sed -i ‘s|etcPath=.*|etcPath=/etc/shifter/shifter_etc_files/|' /etc/shifter/udiRoot.conf sed -i 's|imagegwapi:5000|localhost:5000|’ /etc/shifter/udiRoot.conf echo “abcdefghijklkmnopqrstuvwxyz0123456” > /etc/munge/munge.key chown munge.munge /etc/munge/munge.key chmod 600 /etc/munge/munge.key runuser -u munge munged
