From e2b491028b1dbfc5b7615ca4d7844d4442843f96 Mon Sep 17 00:00:00 2001 From: Douglas Holt Date: Fri, 20 Feb 2026 10:34:39 -0700 Subject: [PATCH] fix: address Copilot review feedback on MAAS deploy and inventory - Move API key validation from maas_auth_header() to load_config() so exit works properly (exit in command substitution only kills subshell) - Accept MAAS_SSH_BASTION env var (consistent with inventory script) and convert to ProxyCommand; MAAS_SSH_PROXY still works as direct override - Quote ssh_bastion value in proxy command to handle spaces/special chars - Use os.environ instead of shell interpolation for network_filter in get_ip() to prevent potential code injection - Deduplicate hosts in inventory when machine has both old and aliased tags (e.g., both kube-master and kube_control_plane) Co-Authored-By: Claude Opus 4.6 (1M context) Signed-off-by: Douglas Holt --- scripts/maas_deploy.sh | 24 ++++++++++++++++++------ scripts/maas_inventory.py | 9 ++++++++- 2 files changed, 26 insertions(+), 7 deletions(-) diff --git a/scripts/maas_deploy.sh b/scripts/maas_deploy.sh index 3e7e4a34..cfef6b8b 100755 --- a/scripts/maas_deploy.sh +++ b/scripts/maas_deploy.sh @@ -15,7 +15,8 @@ # Configuration: # Reads config/maas-inventory.yml (same config as maas_inventory.py). # Environment variables override config file values: -# MAAS_API_URL, MAAS_API_KEY, MAAS_MACHINES, MAAS_SSH_USER, MAAS_SSH_PROXY +# MAAS_API_URL, MAAS_API_KEY, MAAS_MACHINES, MAAS_SSH_USER, +# MAAS_SSH_BASTION (or MAAS_SSH_PROXY for full ProxyCommand override) # # Examples: # ./scripts/maas_deploy.sh --os noble --profile k8s @@ -69,13 +70,18 @@ load_config() { api_url) [[ -z "${MAAS_API_URL:-}" ]] && MAAS_API_URL="$value" ;; api_key) [[ -z "${MAAS_API_KEY:-}" ]] && MAAS_API_KEY="$value" ;; ssh_user) [[ -z "${MAAS_SSH_USER:-}" ]] && MAAS_SSH_USER="$value" ;; - ssh_bastion) [[ -z "${MAAS_SSH_PROXY:-}" ]] && MAAS_SSH_PROXY="ssh -W %h:%p -q ${value}" ;; + ssh_bastion) [[ -z "${MAAS_SSH_PROXY:-}" && -z "${MAAS_SSH_BASTION:-}" ]] && MAAS_SSH_BASTION="$value" ;; network) [[ -z "${MAAS_NETWORK:-}" ]] && MAAS_NETWORK="$value" ;; machines) [[ -z "${MAAS_MACHINES:-}" ]] && MAAS_MACHINES="$value" ;; esac done < "$config_file" fi + # Build SSH proxy from MAAS_SSH_BASTION if MAAS_SSH_PROXY not set directly + if [[ -z "${MAAS_SSH_PROXY:-}" && -n "${MAAS_SSH_BASTION:-}" ]]; then + MAAS_SSH_PROXY="ssh -W %h:%p -q ${MAAS_SSH_BASTION}" + fi + # Defaults for anything still unset MAAS_API_URL="${MAAS_API_URL:-}" MAAS_API_KEY="${MAAS_API_KEY:-}" @@ -95,6 +101,12 @@ load_config() { echo "Set it in config/maas-inventory.yml or as an environment variable" exit 1 fi + + # Validate API key format: exactly 3 non-empty colon-separated parts + if [[ !
