You can perform an airgapped installation on Docker.

Install yb-voyager using a Docker image in an airgapped environment using the following steps:

  1. From a machine connected to the internet, run the following commands to pull and save the latest yb-voyager docker image (Pull the version from docker.io):

    docker pull yugabytedb/yb-voyager
docker save -o yb-voyager-image.tar yugabytedb/yb-voyager:latest
gzip yb-voyager-image.tar

  2. Download the yb-voyager wrapper script on the same machine using the following command:

    wget -O ./yb-voyager https://raw.githubusercontent.com/yugabyte/yb-voyager/main/docker/yb-voyager-docker

  3. Copy the yb-voyager-image.tar.gz and yb-voyager files to the airgapped machine.

  4. Load the docker image using the following command:

    gunzip yb-voyager-image.tar.gz
docker load --input yb-voyager-image.tar

  5. Make the wrapper script executable and move it to the bin directory using the following commands:

    chmod +x yb-voyager
sudo mv yb-voyager /usr/local/bin

  6. Check that yb-voyager is installed using the following command:

    yb-voyager version

You can perform an airgapped installation on RHEL 8 and CentOS 8.

  1. Download the airgapped bundle:

    https://s3.us-west-2.amazonaws.com/downloads.yugabyte.com/repos/airgapped/yb-voyager-latest-rhel-8-x86_64.tar.gz

  2. Extract the bundle.

    tar -xvf <tar-bundle-name>

    It contains three packages - debezium, ora2pg, and yb-voyager.

  3. Download the airgapped installation script into the extracted bundle directory:

    wget -P </path/to/directory> raw.githubusercontent.com/yugabyte/yb-voyager/main/installer_scripts/install-voyager-airgapped.sh

  4. Make the script executable:

    chmod +x /path/to/directory/install-voyager-airgapped.sh

  5. Transfer the folder (which contains the 3 packages and the installer script) to the airgapped machine.

  6. Install all the dependencies on the airgapped machine.

  7. Run the installer script on the airgapped machine to check the dependencies and install voyager:

    ./install-voyager-airgapped.sh

  8. Check that yb-voyager is installed using the following command:

    yb-voyager version
