You can choose one of the following installation options:
- Run as standalone binary
- Run as docker container
- Kubernetes with helm chart
Prepare your configuration
Blocky supports single or multiple YAML files as configuration. Create new
config.yaml with your configuration (
see Configuration for more details and all configuration options).
Simple configuration file, which enables only basic features:
upstream: default: - 184.108.40.206 - 220.127.116.11 - tcp-tls:fdns1.dismail.de:853 - https://dns.digitale-gesellschaft.ch/dns-query blocking: blackLists: ads: - https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts clientGroupsBlock: default: - ads port: 53 httpPort: 4000
Run as standalone binary
Download the binary file from GitHub for your architecture and
./blocky --config config.yml.
Please be aware, if you want to use port 53 or 953 on Linux you should add CAP_NET_BIND_SERVICE capability to the binary or run with root privileges (running as root is not recommended).
Run with docker
Blocky docker images are deployed to DockerHub (
spx01/blocky) and GitHub Container Registry (
You can define the location of the config file in the container with environment variable "CONFIG_FILE". Default value is "/app/config.yml".
Docker from command line
Execute following command from the command line:
docker run --name blocky -v /path/to/config.yml:/app/config.yml -p 4000:4000 -p 53:53/udp spx01/blocky
Run with docker-compose
version: "2.1" services: blocky: image: spx01/blocky container_name: blocky restart: unless-stopped ports: - "53:53/tcp" - "53:53/udp" - "4000:4000/tcp" environment: - TZ=Europe/Berlin # Optional to synchronize the log timestamp with host volumes: # config file - ./config.yml:/app/config.yml
and start docker container with
docker-compose up -d
Following example shows, how to run blocky in a docker container and store query logs on a SAMBA share. Local black and whitelists directories are mounted as volume. You can create own black or whitelists in these directories and define the path like '/app/whitelists/whitelist.txt' in the config file.
version: "2.1" services: blocky: image: spx01/blocky container_name: blocky restart: unless-stopped ports: - "53:53/tcp" - "53:53/udp" - "4000:4000/tcp" # Prometheus stats (if enabled). environment: - TZ=Europe/Berlin volumes: # config file - ./config.yml:/app/config.yml # write query logs in this volume - queryLogs:/logs # put your custom white and blacklists in these directories - ./blacklists:/app/blacklists/ - ./whitelists:/app/whitelists/ volumes: queryLogs: driver: local driver_opts: type: cifs o: username=USER,password=PASSWORD,rw device: //NAS_HOSTNAME/blocky
Multiple configuration files
For complex setups, splitting the configuration between multiple YAML files might be desired. In this case, folder containing YAML files is passed on startup, Blocky will join all the files.
./blocky --config ./config/
Blocky simply joins the multiple YAML files. If a directive (e.g.
upstream) is repeated in multiple files, the configuration will not load and start will fail.
