Installing the Docker engine

If you wish to deploy Db2® Warehouse on a system that does not have an internet connection, you must first install the Docker Engine on that system.

Before you begin

In addition to access to the system on which Db2 Warehouse is to be deployed, you will require access to a system that is connected to the internet so that you can download the necessary packages.
This procedure describes how to install Docker Version 18.09.03 on Red Hat Enterprise Linux 7.5 (RHEL 7.5). If you are using a different Docker version or a different operating system, you will need to adjust the package names accordingly. Supported Docker versions and operating systems are described in IBM Db2 Warehouse prerequisites.

Procedure

On a system with an internet connection, run the following commands to download the necessary packages¹:

# Main docker-ce package and its dependents 
wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.09.03.el7.x86_64.rpm 
wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-cli-18.09.03.el7.x86_64.rpm 
wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.03.el7.x86_64.rpm

wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libseccomp-2.3.1-3.el7.x86_64.rpm 
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libsemanage-python-2.514.el7.x86_64.rpm 
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/policycoreutils-python-2.529.el7.x86_64.rpm

wget http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.681.el7.noarch.rpm

Transfer the packages to the system to which Db2 Warehouse is to be deployed (the target system).

On the target system, run the following commands in the order shown to install or upgrade the packages:

rpm -ivh containerd.io-1.2.0-3.el7.x86_64.rpm
rpm -ivh libtool-ltdl-2.4.2-22.el7_3.x86_64.rpm
rpm -ivh docker-ce-cli-18.09.0-3.el7.x86_64.rpm
rpm -Uvh audit-2.8.4-4.el7.x86_64.rpm audit-libs-2.8.4-4.el7.x86_64.rpm
rpm -Uvh libsepol-2.5-10.el7.x86_64.rpm
rpm -Uvh libselinux-2.5-14.1.el7.x86_64.rpm libselinux-python-2.5-14.1.el7.x86_64.rpm libselinux-utils-2.5-14.1.el7.x86_64.rpm
rpm -Uvh libsemanage-2.5-14.el7.x86_64.rpm
rpm -Uvh policycoreutils-2.5-29.el7.x86_64.rpm
rpm -ivh libsemanage-python-2.5-14.el7.x86_64.rpm
rpm -ivh audit-libs-python-2.8.4-4.el7.x86_64.rpm
rpm -ivh setools-libs-3.3.8-4.el7.x86_64.rpm
rpm -ivh python-IPy-0.75-6.el7.noarch.rpm
rpm -ivh checkpolicy-2.5-8.el7.x86_64.rpm
rpm -ivh libseccomp-2.3.1-3.el7.x86_64.rpm
rpm -ivh libcgroup-0.41-20.el7.x86_64.rpm
rpm -ivh policycoreutils-python-2.5-29.el7.x86_64.rpm
rpm -ivh container-selinux-2.68-1.el7.noarch.rpm
rpm -ivh docker-ce-18.09.0-3.el7.x86_64.rpm

If Docker is not already configured to use the overlay2 storage driver, configure it as described in Use the OverlayFS storage driver.
On the target system, issue the following commands to create a new directory and open a new file for the Docker storage configuration settings:
```
mkdir -p /etc/docker/
vi /etc/docker/daemon.json
```
Insert the following text, then save the file:
```
{
"storage-driver": "devicemapper",
"storage-opts": [ "dm.basesize=20G" ]
}
```
On the target system, issue the following command to start the Docker engine:
```
systemctl start docker
```
