Air gap environment preparation#

This topic provides guidance for preparing an air-gapped environment and installing an air-gapped environment system for a straightforward installation of Package Security Manager, as detailed in Air gap installation.

Preparing the air-gapped environment#

Hardware requirements#

  • CPU - 4 cores

  • 16GB RAM

  • 1.5TB storage space

    • Conda_air gap zip file is ~1.1TB

    • CVE zip file is ~100MB

When partitioning space, allocate 20GB for /var/lib and the remaining 1.5TB for /opt/anaconda.

Software requirements#

The installer is a self-extracting binary that contains all the necessary components to run Package Security Manager services. The basic requirements prior to installation are:

  • Any Linux variant capable of supporting Docker

  • Use a fully qualified domain name (FQDN) or Hostname

  • DNS record and TLS/SSL certs

  • Make sure that SELinux is not in enforcing mode, either by disabling it or putting it in permissive mode in the /etc/selinux/config file. If it is in enforcing mode, you will need to reboot your instance after updating. After rebooting, run the following command to verify that SELinux is not being enforced:

# The result should be either Disabled or Permissive
getenforce
Complete the Podman setup

Podman setup requires you to download and configure the podman-docker package. This package converts docker commands into their corresponding podman commands.

Note

You might need to work with your IT department to secure the podman-docker package.

  1. Install the required software by running the following commands:

    sudo yum install -y podman-docker
sudo yum install netavark
curl -SL https://github.com/docker/compose/releases/download/v2.23.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

  2. Using your preferred file editor, open the usr/share/containers/containers.conf file and verify the network_backend= value is set to "netavark". If it is not, set the value now, and save your changes.

  3. If necessary, make your docker-compose volume executable by running the following command:

    sudo chmod +x /usr/local/bin/docker-compose

  4. Create a symbolic link by running the following command:

    sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

  5. Enable the podman.socket by running the following commands:

    sudo systemctl enable --now podman.socket
sudo systemctl status podman.socket

  6. Verify that the podman socket works by running the following command:

    sudo curl -w "\n" -H "Content-Type: application/json" --unix-socket /var/run/docker.sock http://localhost/_ping

Downloading packages and CVE files#

Artifact download authorization#

Anaconda supplies air-gapped customers with our repository in the form of tarball files. In order to gain access to the tarball files that contain the conda packages and CVEs, you must provide Anaconda with the IP address of the machine you are using to download them. Speak with your Anaconda implementation team member to get help allowlisting your IP address.

Note

This must be completed prior to scheduling your implementation with Anaconda. The download may take several hours.

If you prefer not to use a hostname, the public IP address of your environment will be required.

Downloading packages and CVEs#

In this section, you will download Package Security Manager packages and CVEs.

Note

Downloading Package Security Manager Packages may take several hours.

Caution

Do not unzip the tarball files you’ve downloaded.

Validating Packages and CVEs#

To ensure that the files you’ve downloaded have not been tampered with, you must verify the integrity of the .zip files by running some commands to generate their SHA-256 cryptographic hashes (or “checksums”) and the cryptographic hashes for their corresponding .sha256 files, then checking the output to be sure they match. Choose a set of commands that corresponds with your setup:

File verification commands

If you downloaded your repository files on a Windows machine, run the following commands to view the hashes for the files:

# Replace <FILE> with a file that you downloaded
Get-FileHash <FILE>.zip -Algorithm SHA256
Get-Content <FILE>.sha256

If you downloaded your repository files on a Linux or MacOS machine, run the following commands to view the hashes for the files:

# Replace <FILE> with a file that you downloaded
sha256sum <FILE>.zip
cat <FILE>.sha256

Note

You must run these commands for each for each file you downloaded.

DNS and TLS/SSL certificate requirements#

Package Security Manager can use certificates to provide transport layer security for the cluster. It is required to have your TLS/SSL certs prior to installation.

You may purchase certificates commercially, use Let’s Encrypt, or generate them using your organization’s internal public key infrastructure (PKI) system. When using an internal PKI-signed setup, the CA certificate is stored on the file system. You will need to make sure the root certificate of your certificate authority is trusted by the server running the application and the workstations used by users of the application.

DNS requirements

Web browsers use domain names and web origins to separate sites, so they cannot tamper with each other. If you want to use DNS, you must have it ready prior to installation. This DNS name is what users will use to access the application.

You must provide the SSL cert for the hostname your Package Security Manager instance is running on.

Security requirements#

External Ports#

These are ports that allow access outside of the server. It is important to protect all services running on the node from outside access. The exceptions are as shown below. These ports need to be open to allow access to Package Security Manager via browser and (optionally) via SSH:

  • :443 nginx - only if you are using HTTPS

  • :22 ssh - optional; only if you need SSH

Internal Ports#

These are ports that allow access within the server and are open on docker containers, exposed only to the docker network. Ideally, Package Security Manager will have a dedicated environment. Package Security Manager uses several ports for internal communication between components. These ports do not need to be open to the end user but they need to be reserved, as some bind to the local host network interfaces.

You can run docker ps and reference the PORTS column, as shown in the following example:

  • :5000 repo - Package Security Manager API

  • :5002 repo-proxy - Package Security Manager file serving API proxy

  • :5000 repo-dispatcher - Package Security Manager event dispatcher/handler (exposed only for Prometheus metrics)

  • :5000 repo-worker - Package Security Manager scheduled jobs worker (exposed only for Prometheus metrics)

  • :8080 keycloak - Keycloak’s /auth/* endpoints are proxied in Nginx

  • :5432 postgres - Postgresql database used by Package Security Manager and Keycloak

  • :6379 redis - Redis instance used by Package Security Manager services

  • :9090 Prometheus - Prometheus is proxied in Nginx at /Prometheus

Enable IP address forwarding#

Forwarding IP addresses allows containers to communicate with one another on your host. You’ll need to configure these settings to allow non-root users to perform installations of Package Security Manager.

sysctl net.ipv4.conf.all.forwarding=1
sysctl net.ipv6.conf.all.forwarding=1
iptables -P FORWARD ACCEPT

System validation checks#

Once your environment is prepared, run the following commands to verify it is ready for installation of Package Security Manager.

System validation

To verify what type of processor your system is running and the number of CPUs present, run the command:

cat /proc/cpuinfo

To verify the amount of system memory is sufficient, run the command:

cat /proc/meminfo

To verify there is a sufficient amount of disk space for the installation, run the command:

df -h

To verify the kernel release version and processor type, run the command:

uname -a

To verify your operating system release version, run the command:

cat /etc/os-release

To verify your version of Docker, run the command:

docker version

To verify your version of docker-compose, run the command:

docker compose --version

After ensuring all requirements have been met, proceed to Air gap installation to install Package Security Manager in your air-gapped environment.
