Creating an Offline Repository

The pgedge repository provides packages that provide a simplified way to install Postgres; you can use a copy of the pgedge repository to create an offline repository for use on systems with restricted internet access.

Creating an offline repository requires two systems:

  • You will need to use an OS compatible system with internet access and a valid pgEdge repository certificate to download and create a live model of the repository.

  • You will need an OS compatible system with access to the machine with internet access; after creating the model on the first host, you will copy the repository to the system without internet access.

You must ensure the system with internet access and the offline target server that will eventually host the repository have the same OS version and architecture.

  1. Create a temporary repository on the online machine with the command:

    dnf install -y https://downloads.pgedge.com/reporpm/pgedge-release-latest.noarch.rpm

  2. Install prerequisite software on the both the host with access and the repository host.

    For Rocky or Alma Linux 9x or 10x (x86_64), use the commands:

    sudo dnf install -y epel-release

    sudo dnf config-manager --set-enabled crb

    For RHEL 9x (x86_64):

    sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

    sudo subscription-manager repos --enable codeready-builder-for-rhel-9-x86_64-rpms

    For RHEL 10 x86_64:

    sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-10.noarch.rpm

    sudo subscription-manager repos --enable codeready-builder-for-rhel-10-x86_64-rpms

  3. Register the online machine and install its certificate, so it can download packages from the pgedge repository. Create the certificate request with the command:

    sudo pgedge-subscription-manager register-system

    Email the client.csr file the command names to support@pgedge.com. When pgEdge returns your certificate, install it with the command:

    sudo pgedge-subscription-manager install complete_path_to/client.crt

    For details, see Obtaining and Installing a Repository Certificate.

  4. Download the content of the pgedge repository:

    sudo dnf -y install --downloadonly --downloaddir=<target_directory>/pgedge-enterprise-all_18 pgedge-*

  5. After creating the model of the repository on the temporary host, you can transfer the entire repo to the offline repository host.

Using the Repository

The offline repository host and the systems that install from it do not need a certificate; only the online machine that downloads the packages does.

To use your local repository, include the localinstall clause when you invoke dnf to install packages. For example, to install all of the pgEdge Enterprise Postgres packages:

sudo dnf localinstall pgedge-enterprise-all_18*

To install just the pgEdge Enterprise Postgres packages:

sudo dnf localinstall pgedge-enterprise-postgres_18*

Or, to install each pgEdge component individually, specify a component name:

sudo dnf localinstall pgedge-spock50_18*
