 # 分布式编译系统CloudBuild

 ##  为什么需要分布式编译技术
 - 大型项目过长的编译耗时将会给开发、测试和调试都带来延迟，所以缩短大型项目的编译时间的分布式编译系统有重要意义
 - 使用分布式编译系统编译项目可以利用计算机集群提高编译效率，缩短项目编译时间

+
+### 分布式编译原理
+![alt text](/public/cloudbuild/compiler-principles.png)
+
+### CloudBuild客户端
+CloudBuild客户端基于Ninja改造，有下面这些优势
+- 兼容使用Ninja编译的项目
+- 使用远程执行的方式提高编译时并发度
+- 使用编译缓存减少需要编译的任务数量
+
+### CloudBuild服务端
+- 使用远程执行的方法提高编译时并发度，实现了任务分发至远程节点同步执行
+- 使用分布式任务调度提高任务调度效率和计算节点资源利用率，避免集中式调度的任务阻塞问题
+- 使用编译缓存结合内容寻址存储技术减少网络传输量、避免重复上传与重复编译
+
+### CloudBuild优势
+- 低成本：组成executor的机器不需要使用专门的高性能计算型机器，可使用多个平价的空闲机器
+- 高效：CloudBuild实现分布式编译的功能，相比单机大大提升并发度
+- 兼容Ninja：CloudBuild客户端基于Ninja改造，对于使用Ninja构建和可以转换为Ninja构建的项目不用额外修改构建清单
+
+### CloudBuild执行流程
+- 客户端: 生成远程任务->生成任务依赖->发送任务与依赖
+- 服务端：检查任务缓存->检查依赖完整性->调度任务
+- 编译结点：还原文件目录->还原文件目录->返回编译结果

-# What is Gitea Runner
-
-Act runner is a runner for Gitea based on [Gitea fork](https://gitea.com/gitea/act) of [act](https://github.com/nektos/act). This documentation is a copy of https://gitea.com/gitea/act_runner/src/branch/main/README.md . And it should be updated once that README changed.
-
-## Installation
-
-### Prerequisites
-
-Docker Engine Community version is required for docker mode. To install Docker CE, follow the official [install instructions](https://docs.docker.com/engine/install/).
-
-### Download pre-built binary
-
-Visit [here](https://dl.gitea.com/act_runner/) and download the right version for your platform.
-
-### Build from source
-
-```bash
-make build
-```
-
-### Build a docker image
-
-```bash
-make docker
-```
-
-### Register
-
-```bash
-./act_runner register
-```
-
-And you will be asked to input:
-
-1. Gitea instance URL, like `http://192.168.8.8:3000/`. You should use your gitea instance ROOT_URL as the instance argument
- and you should not use `localhost` or `127.0.0.1` as instance IP;
-2. Runner token, you can get it from `http://192.168.8.8:3000/-/admin/actions/runners`;
-3. Runner name, you can just leave it blank;
-4. Runner labels, you can just leave it blank.
-
-The process looks like:
-
-```text
-INFO Registering runner, arch=amd64, os=darwin, version=0.1.5.
-WARN Runner in user-mode.
-INFO Enter the Gitea instance URL (for example, https://gitea.com/):
-http://192.168.8.8:3000/
-INFO Enter the runner token:
-fe884e8027dc292970d4e0303fe82b14xxxxxxxx
-INFO Enter the runner name (if set empty, use hostname: Test.local):
-
-INFO Enter the runner labels, leave blank to use the default labels (comma-separated, for example, ubuntu-latest:docker://gitea/runner-images:ubuntu-latest):
-
-INFO Registering runner, name=Test.local, instance=http://192.168.8.8:3000/, labels=[ubuntu-latest:docker://gitea/runner-images:ubuntu-latest ubuntu-22.04:docker://gitea/runner-images:ubuntu-22.04 ubuntu-20.04:docker://gitea/runner-images:ubuntu-20.04].
-DEBU Successfully pinged the Gitea instance server
-INFO Runner registered successfully.
-```
-
-You can also register with command line arguments.
-
-```bash
-./act_runner register --instance http://192.168.8.8:3000 --token <my_runner_token> --no-interactive
-```
-
-If the registry succeed, it will run immediately. Next time, you could run the runner directly.
-
-### Run
-
-```bash
-./act_runner daemon
-```
-
-### Run with docker
-
-```bash
-docker run -e GITEA_INSTANCE_URL=https://your_gitea.com -e GITEA_RUNNER_REGISTRATION_TOKEN=<your_token> -v /var/run/docker.sock:/var/run/docker.sock --name my_runner gitea/act_runner:nightly
-```
-
-### Configuration
-
-You can also configure the runner with a configuration file.
-The configuration file is a YAML file, you can generate a sample configuration file with `./act_runner generate-config`.
-
-```bash
-./act_runner generate-config > config.yaml
-```
-
-You can specify the configuration file path with `-c`/`--config` argument.
-
-```bash
-./act_runner -c config.yaml register # register with config file
-./act_runner -c config.yaml daemon # run with config file
-```
-
-You can read the latest version of the configuration file online at [config.example.yaml](internal/pkg/config/config.example.yaml).
-
-### Example Deployments
-
-Check out the [examples](https://gitea.com/gitea/act_runner/src/branch/main/examples) directory for sample deployment types.
