Installation

To build a S2I base image, choose either the CentOS or RHEL based image:

• RHEL based image

  This image is available in Red Hat Container Registry. To download it run:

  $ podman pull registry.access.redhat.com/rhscl/s2i-base-rhel7
  

  Or

  $ podman pull registry.access.redhat.com/rhscl/s2i-core-rhel7
  

  To build a RHEL based S2I base image, you need to run the build on a properly subscribed RHEL machine.

  $ git clone --recursive https://github.com/sclorg/s2i-base-container.git
  $ cd s2i-base-container
  $ git submodule update --init
  $ make build TARGET=rhel7 VERSIONS=base
  

• CentOS based image

  This image is available on DockerHub. To download it run:

  $ podman pull quay.io/centos7/s2i-base-centos7
  

  Or

  $ podman pull quay.io/centos7/s2i-core-centos7
  

  To build a S2I base image from scratch run:

  $ git clone --recursive https://github.com/sclorg/s2i-base-container.git
  $ cd s2i-base-container
  $ git submodule update --init
  $ make build TARGET=centos7 VERSIONS=base
  

Note: while the installation steps are calling podman, you can replace any such calls by docker with the same arguments.

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all provided versions of S2I base image.
