How to run offline Docker SCDM installation

Summary

This document provides the steps for Docker SCDM offline installation.

Step By Step

Install Docker repository on the machine that has internet access:

Install Docker registry server

Make sure this host has the hostname resolved in DNS. 

https://docs.docker.com/engine/installation/linux/docker-ce/centos/#install-using-the-repository

 

$ docker run -d -p 5000:5000 --name registry registry:2

# repository with TLS support, see doc
# example:
# docker run -d -p 5000:5000 --restart=always --name registry -v /certs:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key  registry:2

Upload Docker images to local docker repository

Pull images from Docker hub:

$ docker pull postgres:8.4

$ docker pull mongo:3.2.12

$ docker login --username catalogic --password catal0gic

$ docker pull catalogicsoftware/discovery

$ docker pull catalogicsoftware/vadp

$ docker pull ibmscdm/scdm

 

 Tag images:

$ docker  tag  ibmscdm/scdm localhost:5000/scdm

$ docker tag mongo:3.2.12 localhost:5000/mongo:3.2.12

$ docker tag postgres:8.4 localhost:5000/postgres:8.4

$ docker tag catalogicsoftware/vadp localhost:5000/vadp

$ docker tag  catalogicsoftware/discovery localhost:5000/discovery

 

 Push Docker images to local registry:

$ docker  push localhost:5000/scdm

$ docker  push localhost:5000/mongo:3.2.12

$ docker  push localhost:5000/postgres:8.4

$ docker  push localhost:5000/vadp

$ docker  push localhost:5000/discovery

 

Download scdm.sh script from the Catalogic support site to your proxy server (this is the same server that runs the Docker registry).

And run installation.

$ bash scdm.sh install

After installation you should see the following file structure:

/etc/scdm
          \_ EULA
          \_ scdm.yml
          \_ scdm.sh

 

Copy entire “scdm” directory to the machine that does not have internet access. The file structure should remain same when placed in the /etc/scdm directory. This machine should have Docker installed.

Update the image name to new images added in your local repository:

# myregistrydomain (example) is FQDN for your registry server, Should be resolvable from your offline machine.

$ REGISTRY=<myregistrydomain:5000>

$ sed -i "s#image: #image: ${REGISTRY}/#g" /etc/scdm/scdm.yml

$ sed -i "s#catalogicsoftware/##g" /etc/scdm/scdm.yml

$ sed -i "s#ibmscdm/##g" /etc/scdm/scdm.yml

Test if you can pull docker image from your local registry:

$ docker pull ${REGISTRY}/scdm

If successful, proceed to start the scdm application:

cd /etc/scdm
./scdm start
