From 8121d37df8b2b0b5e00293ffee28a9616191e01b Mon Sep 17 00:00:00 2001 From: Joshua Gilman Date: Mon, 29 Dec 2025 20:50:22 -0800 Subject: [PATCH] fix(vyos): use native load command for Ansible deployments MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The vyos.vyos.vyos_config Ansible module claims to support bracket format configuration files but has two critical bugs: 1. Doesn't parse /* */ comments (treats them as commands) 2. Incorrectly converts bracket format to set commands This change switches to using VyOS's native `load` command which properly handles bracket format with comments - the same approach used for manual USB provisioning. Changes: - Rewrite deploy.yml to SCP config to router and use `load` command - Add .gitignore for rendered configs and backup artifacts - Add eth2 interface definition to gateway.conf 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- infrastructure/network/vyos/.gitignore | 10 + .../network/vyos/ansible/playbooks/deploy.yml | 175 ++++++++++++------ .../network/vyos/configs/gateway.conf | 3 + .../network/vyos/tests/render-config-boot.sh | 9 +- 4 files changed, 132 insertions(+), 65 deletions(-) create mode 100644 infrastructure/network/vyos/.gitignore diff --git a/infrastructure/network/vyos/.gitignore b/infrastructure/network/vyos/.gitignore new file mode 100644 index 0000000..e37adae --- /dev/null +++ b/infrastructure/network/vyos/.gitignore @@ -0,0 +1,10 @@ +# Rendered config contains secrets - never commit +.rendered-gateway.conf + +# Backups are local artifacts +backups/ + +# Test artifacts +tests/.vyos-test-key +tests/.vyos-test-key.pub +tests/config.boot diff --git a/infrastructure/network/vyos/ansible/playbooks/deploy.yml b/infrastructure/network/vyos/ansible/playbooks/deploy.yml index b4cf32f..604f587 100644 --- a/infrastructure/network/vyos/ansible/playbooks/deploy.yml +++ b/infrastructure/network/vyos/ansible/playbooks/deploy.yml @@ -1,16 +1,25 @@ # VyOS Configuration Deployment Playbook -# Applies gateway.conf to VyOS with rollback protection +# Applies gateway.conf to VyOS router using native VyOS `load` command # # Usage: # ansible-playbook deploy.yml -i ../inventory/hosts.yml -# ansible-playbook deploy.yml -i ../inventory/hosts.yml -e "ssh_public_key_file=~/.ssh/id_rsa.pub" # # Environment Variables: -# VYOS_HOST - VyOS hostname or IP (default: gateway.lab.gilman.io) -# VYOS_SSH_KEY - Path to SSH private key for connection (default: ~/.ssh/id_rsa) +# VYOS_HOST - VyOS hostname or IP (default: 10.0.0.2) +# VYOS_SSH_KEY - Path to SSH private key for connection (default: ~/.ssh/vyos-gateway) # -# Extra Variables: -# ssh_public_key_file - Path to SSH public key to configure on VyOS (optional) +# This playbook: +# 1.
