Vagrant — Behind Proxy & Firewall

# Install vagrant-proxyconf plugin

# Download box
vagrant box add generic/oracle8

# Or use a locally cached box file
# Download the box file manually using a browser/curl from outside network
# Then add it locally
vagrant box add oel8-local /path/to/downloaded/oracle8.box

# For Parallels — use metadata JSON
vagrant box add /path/to/box-metadata.json

# Step 1 — On a machine WITH internet access:
# Download box
vagrant box add generic/oracle8 --provider virtualbox
# Box is saved at: ~/.vagrant.d/boxes/generic-VAGRANTSLASH-oracle8/

# Download RPM packages needed for provisioning
mkdir -p ~/offline-rpms
dnf download --resolve --destdir ~/offline-rpms   mysql-community-server mysql-community-client

# Step 2 — Transfer to air-gapped machine:
# Copy ~/.vagrant.d/boxes/ directory
# Copy ~/offline-rpms/ directory
rsync -avz ~/.vagrant.d/boxes/ airgapped-machine:~/.vagrant.d/boxes/
rsync -avz ~/offline-rpms/ airgapped-machine:~/offline-rpms/

# Step 3 — On air-gapped machine:
# Use local RPMs in provisioner
vagrant up

# In provisioner script — install from local RPMs
dnf localinstall -y /vagrant/offline-rpms/*.rpm

# Proxy with username and password
export http_proxy="http://username:password@proxy.company.com:8080"
