Minimal kamailio image with enhancements including running the database in ram. This image uses a custom, minimal version of Debian Linux.
The build environment has been split off from this repo and now lives @ https://github.com/telephoneorg/kamailio-builder. See the README.md file there for more details on the build environment.
The installation environment is used for configuring which modules are installed from our custom packages.
KAMAILIO_INSTALL_MODS
The following variables are standard in most of our dockerfiles to reduce duplication and make scripts reusable among different projects:
APP
: kamailioUSER
: kamailioHOME
/opt/kamailio
Run environment variables are used in the entrypoint script to render configuration templates, perform flow control, etc. These values can be overridden when inheriting from the base dockerfile, specified during docker run
, or in kubernetes manifests in the env
array.
PUBLIC_IPV4
PUBLIC_FQDN
DOMAIN_NAME
KAMAILIO_LOG_LEVEL
KAMAILIO_LOG_COLOR
KAMAILIO_MY_HOSTNAME
KAMAILIO_MY_IP_ADDRESS
KAMAILIO_MY_WEBSOCKET_DOMAIN
KAMAILIO_AMQP_HOSTS
RABBITMQ_USER
RABBITMQ_PASS
KAMAILIO_SHM_MEMORY
KAMAILIO_PKG_MEMORY
KAMAILIO_CHILD_PROC
KAMAILIO_MTU
KAMAILIO_ENABLE_ROLES
SYNC_FREESWITCH_SOURCE
SYNC_FREESWITCH_ARGS
[todo] Finish describing these.
All of our docker-* repos in github have CI pipelines that push to docker cloud/hub.

NOTE: Please reference the Run Environment section for the list of available environment variables.
NOTE: In production, you may want to run this container in the host's networking stack. In that case remove the port mappings above and insert --net=host
. Under Kubernetes, if you are using our manifests, this is already taken care of.
Pull the images
docker-compose pull
Start application and dependencies
# start in foreground
docker-compose up --abort-on-container-exit
# start in background
docker-compose up -d
Edit the manifests under kubernetes/<environment>
to reflect your specific environment and configuration.
Create a secret for the erlang cookie:
kubectl create secret generic erlang --from-literal=erlang.cookie=$(LC_ALL=C tr -cd '[:alnum:]' < /dev/urandom | head -c 64)
Create a secret for the kamailio credentials:
kubectl create secret generic kamailio --from-literal=kamailio.user=$(sed $(perl -e "print int rand(99999)")"q;d" /usr/share/dict/words) --from-literal=kamailio.pass=$(LC_ALL=C tr -cd '[:alnum:]' < /dev/urandom | head -c 32)
Deploy kamailio:
kubectl create -f kubernetes
