FAQ

How to get started?

Make sure to install ansible and clone the bbb-configs repository. Then install the requirements using:

python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt

How to spin up a config run?

ansible-playbook play.yml

This will generate config files for all devices for inspection. The output path is /tmp/ansible-openwrt/configs.

How to spin up a config run and image generation?

ansible-playbook play.yml --tags image

The output path for the images is /tmp/ansible-openwrt/images.

How to limit a config and image generation?

# config run
ansible-playbook play.yml --limit example-core # single-device
ansible-playbook play.yml --limit example-* # location
ansible-playbook play.yml --limit example-core,example-ap1 # list of specific devices

# config run and image generation
ansible-playbook play.yml --limit example-core --tags image # single-device
ansible-playbook play.yml --limit example-* --tags image # location
ansible-playbook play.yml --limit example-core,example-ap1 --tags image # list of specific devices

The second command doesn't work in zsh. If you encounter that problem consider using bash instead, please.

How to spin up a config run, image generation and flash from inside freifunk network?

NOTE: This requires IPv6 Connectivity from inside the freifunk network and is not yet fully working.

ansible-playbook play.yml --tags flash

What is required to bringup a location?

  1. Create a location folder at /group_vars/ and fill in at least general.yml, networks.yml and owm.yml.
  2. Create a folder for every OpenWrt device at the location under /host_vars/. Paste the base.yml in there.
  3. Run the image creation as shown in the commands above (image will be in /tmp/ansible-openwrt/images/).
  4. Flash the image to your router.
  5. Secure the router by setting a root password using SSH or the web interface.
  6. Done!

Have a look at the Developers Guide for more information.

What is required to send in a pull request?

Make sure to test your addition with yamllint and ansible-lint before sending a pull request by using:

yamllint -d .config/yaml-lint.yml .
ansible-lint -c .config/ansible-lint.yml

How can I mass deploy in the Freifunk Network

# Find groups matching our targets to ease selection
ansible-inventory --graph

# Generate images for a list of specific devices
ansible-playbook play.yml --tags image --limit example-core,example-ap1

# Change into images directory
cd /tmp/ansible-openwrt/images

# Optional: Keyscan for hostkeys
for i in *.bin; do hostname="$(echo $i | awk -F '.' '{print $1}')"; ssh_target="$hostname.olsr"; ssh-keyscan "$ssh_target"; done

# "oneliner" to mass-flash all devices where we have an image (use with caution)
for i in *.bin; do hostname="$(echo $i | awk -F '.' '{print $1}')"; ssh_target="root@$hostname.olsr"; path="/tmp/$i"; echo -e "\e[92m$(date +%H:%M:%S) - $hostname: Disabling non-mesh wireless networks to free memory and sleep 13 seconds until change is applied (required for 32mb devices)\e[0m"; ssh "$ssh_target" "for i in \$(uci show wireless | grep mode=\'ap\' | awk -F '.'
