+# ha-api
+
+## Introduction
+REST API backend for HA manage platform.
+
+Another project is [HA-web](https://gitee.com/openeuler/ha-web), providing frontend UI for HA manage platform.
+
+## Screenshots
+
+TODO: add some screenshots here
+
+## Features
+
+Easy to use.
+
+## Documents
+
+The following documents are provided to help you understand the project:
+ - [Build Document](./docs/build_en.md)
+ - [Architecture Document](./docs/architecture_en.md)
+ - [API Document](./docs/api_en.md)
+
+## Installation
+
+HA software is needed to run backend of ha-api manage platform .
+
+In openEuler 20.03 LTS SP1, you can install HA software by yum:
+
+```
+[root@ha1~]# yum install corosync pacemaker pcs fence-agents fence-virt corosync-qdevice sbd drbd drbd-utils
+```
+
+For another OS, you may need to compile it and then install.
+You can get more details in [install documents](./docs/install_en.md) and [build documents](./docs/build_en.md)
+
+## Contribution
+
+HA-api is developed with golang. We use [Beego framework](https://beego.me/) to help us to develop high performance and reliable manage platform. All contributions are welcomed. If you have any problems in using or developing, please contact us by submitting a issue.
+
+
+## Gitee Feature
+
+1. You can use Readme\_XXX.md to support different languages, such as Readme\_en.md, Readme\_zh.md
+2. Gitee blog: [blog.gitee.com](https://blog.gitee.com)
+3. You can explore open source project: [https://gitee.com/explore](https://gitee.com/explore)
+4. The Gitee Most Valuable Project ([GVP](https://gitee.com/gvp)), the excellent open source project comprehensively evaluated by Gitee
+5. The manual of Gitee: [https://gitee.com/help](https://gitee.com/help)
+6. The most popular Gitee members: [https://gitee.com/gitee-stars/](https://gitee.com/gitee-stars/)

+# embedded
+
+#### 1 Introduction
+
+This openEuler version supports embedded devices and currently supports [aarch64|x86_64] CPU architectures
+
+#### 2 Compilation Instructions
+
+The compilation entry: build.sh
+
+```Usage:
+Usage:
+
+./build.sh -a [aarch64|x86_64] -r [repo] -d [work dir] -p [live|virtual|disk|docker] -t [rpm|image|all]
+```
+
+The role of each parameter is described as follows.
+
+1)-r,specifies the repo file, in the format of the dnf/yum, see [Document 1](https://docs.openeuler.org/zh/docs/20.03_LTS/docs/Administration/%E4%BD%BF%E7%94%A8DNF%E7%AE%A1%E7%90%86%E8%BD%AF%E4%BB%B6%E5%8C%85.html "使用DNF管理软件包").
+
+2)-d,specifies the working directory used in the compilation process, where all intermediate files and the results are stored. As the compilation process requires a large amount of disk space, this directory should be located on a disk with **more than 20G** remaining space.
+
+3)-p,specifies the type of image to be compiled, currently docker image is stably supported.
+
+4)-t,specifies the compilation type, "rpm" means compile the rpm repository according to the source code and patch; "image" means compile the specified image according to the given repo; "all" will execute the compilation process specified by rpm and image in order.
+
+5)-a,no need to specify, set aside parameters to support cross-compilation.
+
+The structure of the working directory (-d specified parameter) during normal compilation is as follows.
+
+```
+allsrcpath.list // list of packages to be compiled according to package_conf.xml
+image/ // the location of image and its description file
+kiwiconfig/
+logs_1.tar.gz // package compilation logs for rounds 1/2
+logs_2.tar.gz // package compilation logs for rounds 2/2
+openeuler.repo
+rpms/ // the directory where the rpm package is compiled, which can be referenced as a repo source
+src/ // download and patch the package source files according to the configuration file
+```
+
+**Note: if the compiled session (login terminal) is prone to disconnections, perform compilation in a manner similar to ```nohup sh build.sh -r ... > log.txt 2>&1 &```** to avoid compilation interruption caused by disconnection.
+
+#### 3 Configuration File Description
+
+The configuration files are located in the config directory:
+
+```
+kiwiconf/
+openeuler.repo
+package_conf.xml
+```
+
+1) ```kiwiconf/```,stores the configuration file required for the kiwicompat command. No changes are normally required.
+
+For the format of the config. XML file, see [Document 2](https://documentation.suse.com/kiwi/9/single-html/kiwi/index.html#image-description-elements "image-description-elements"), [Document 3](https://documentation.suse.com/kiwi/9/html/kiwi/image-description.html "image-description").
+
+After creating the system directory kiwi, calls images.sh. This script can be used to trim unnecessary files from the root directory or to make some system settings. Some of the predefined functions and variables to the script are described in [Document 4](https://documentation.suse.com/kiwi/9/single-html/kiwi/index.html#script-template-for-config-sh-images-sh "script-template-for-config-sh-images-sh").
+
+2)```openeuler.repo```,the reserved repo file, generally used in the `-r` parameter of build.sh.
+
+3)```package_conf.xml```,the package configuration that needs to be patched with git format-patch and to be compiled for source code, with an example to illustrate the role of each tag.
+
+```

+
+ argon2
+ https://gitee.com/openeuler-embedded/argon2
+ openEuler-20.03-LTS
+ ../src/patch/argon2.patch
+ 1
+
+
+ attr
+ https://gitee.com/openeuler-embedded/attr
+ openEuler-20.03-LTS
+ ../src/patch/attr.patch
+ 1
+
+ ......
+```
+
+#### 4 Example of Image Usage
+
+Take the docker image as an example, the image is located in the image path of the working directory named openEuler-embedded.xxx-xxx.docker.tar.xz.
+
+```shell
+docker load -i openEuler-embedded.xxx-xxx.docker.tar.xz
+docker run --rm --privileged --name embedded-test -v `pwd`:/data -itd openeuler-embedded init
+docker exec -it embedded-test bash
+```
+
+#### 5 Dependencies
+
+1)kiwi >= 9.21
+
+2)docker/chroot/createrepo/xmllint/openssl
+
+#### 6 TODO
+
+As of now, rpm package compilation and docker image creation is working stably.
+
+Further improve:
+
+1)diversification support, such as virtual machine images and embedded device images, etc.
+
+2)rpm build scheduling module to build all packages correctly based on automatically identified dependencies.
+
+3)cross-compilation support
