21 | 22 | 23 | --- 24 | 25 | 26 | 27 | ## About 28 | 29 | A globally distributed, edge container image registry that leverages the power of Cloudflare's global network. Providing `docker pull`'s 3x faster than DockerHub, Containerflare offers a unique solution for developers looking to distribute their container images worldwide efficiently. 30 | 31 | ## Features 32 | 33 | - **Global Distribution**: Utilize Cloudflare's vast network to pull container images from the edge, closest to where they are needed 34 | - **High Performance**: Experience speeds up to 3x faster than DockerHub, reducing the time it takes to download and deploy container images 35 | - **Built with Astro**: Containerflare is developed using the Astro web framework, ensuring a modern and efficient web application 36 | - **Cloudflare Pages Hosting**: By being hosted on Cloudflare Pages, Containerflare benefits from the additional speed and reliability inherent to the platform 37 | 38 | ## Demo 39 | 40 | Use the publicly hosted instance at [cfcr.dev](https://cfcr.dev): 41 | 42 | ```console 43 | docker pull cfcr.dev/hello-world 44 | ``` 45 | 46 | ## Development 47 | 48 | Containerflare can be run locally for either further development or customization. 49 | 50 | > [!NOTE] 51 | > **BEFORE** you run the following steps make sure: 52 | > - You have Node installed locally on you machine 53 | > - You have `docker` & `docker-compose` installed and running 54 | 55 | ```shell 56 | # Clone the repository 57 | git clone https://github.com/MNThomson/containerflare.git && cd containerflare 58 | 59 | # To start developing, run containerflare 60 | npm start 61 | ``` 62 | 63 | The development environment is now running and accesible at https://localhost:4321/ 64 | 65 | To benchmark the implementation: 66 | 67 | ```shell 68 | # Build the empty container (so there is no docker cache effecting results) 69 | cd dev && make build 70 | 71 | # Run the empty container 72 | make run 73 | 74 | # Within the container shell run the command to pull from the locally running containerflare instance 75 | pull 76 | ``` 77 | -------------------------------------------------------------------------------- /astro.config.mjs: -------------------------------------------------------------------------------- 1 | import cloudflare from "@astrojs/cloudflare"; 2 | import { defineConfig } from "astro/config"; 3 | 4 | // https://astro.build/config 5 | export default defineConfig({ 6 | publicDir: "./src/public", 7 | site: `https://cfcr.dev`, 8 | output: "server", 9 | adapter: cloudflare({ 10 | mode: "directory", 11 | runtime: { mode: "local", persistTo: ".wrangler/state/v3" }, 12 | }), 13 | }); 14 | -------------------------------------------------------------------------------- /dev/Makefile: -------------------------------------------------------------------------------- 1 | run: 2 | docker run -d --privileged --name containerflare-dev mnthomson/containerflare:dev 3 | docker exec -it containerflare-dev /bin/sh 4 | make kill 5 | 6 | kill: 7 | docker kill containerflare-dev 8 | docker rm containerflare-dev 9 | 10 | build: 11 | docker build -t mnthomson/containerflare:dev -f dockerfile.dev . 12 | -------------------------------------------------------------------------------- /dev/dockerfile.dev: -------------------------------------------------------------------------------- 1 | FROM docker:20.10-dind 2 | 3 | RUN mkdir -p /etc/docker && echo '{"insecure-registries" : ["172.17.0.1:8788"]}' > /etc/docker/daemon.json && \ 4 | mkdir -p /etc/default && echo 'DOCKER_OPTS="--config-file=/etc/docker/daemon.json"' > /etc/default/docker 5 | 6 | ADD pull /usr/local/bin 7 | 8 | CMD ["dockerd-entrypoint.sh"] 9 | -------------------------------------------------------------------------------- /dev/pull: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | docker run 172.17.0.1:8788/hello-world:latest 4 | -------------------------------------------------------------------------------- /dev/upload.sh: -------------------------------------------------------------------------------- 1 | rm -f upload.kv 2 | touch upload.kv 3 | echo "[" >> upload.kv 4 | 5 | echo " {" >> upload.kv 6 | echo " \"key\": \"hello-world:latest\"," >> upload.kv 7 | 8 | echo " \"value\": \"$(cat ./.mf/kv/hello-world/latest)\"" >> upload.kv 9 | echo " }," >> upload.kv 10 | 11 | # https://developers.cloudflare.com/workers/wrangler/commands/#kvbulk 12 | for file in ./.mf/kv/sha256/*; do 13 | if [[ -f "$file" && !
