数据平面API
HAProxy
数据平面 API是一个在 HAProxy 旁边运行的 sidecar 进程，并提供用于管理 HAProxy 的 API 端点。它需要 HAProxy 版本 1.9.0 或更高版本。
为了构建数据平面 API，您需要在系统上安装 Go 并启用 go 模块支持，并执行以下步骤：
1.克隆dataplaneapi存储库
git clone https://github.com/haproxytech/dataplaneapi.git
2.运行make build：
make build
3. 您可以在/build目录中找到构建的二进制文件。测试
基本用法：
Usage:
dataplaneapi [OPTIONS]
API for editing and managing haproxy instances
Application Options:
--scheme= the listeners to enable, this can be repeated and defaults to the schemes in the swagger spec
--cleanup-timeout= grace period for which to wait before killing idle connections (default: 10s)
--graceful-timeout= grace period for which to wait before shutting down the server (default: 15s)

--tls-certificate= the certificate to use for secure connections [$TLS_CERTIFICATE]
--tls-key= the private key to use for secure connections [$TLS_PRIVATE_KEY]
--tls-ca= the certificate authority file to be used with mutual tls auth [$TLS_CA_CERTIFICATE]
--tls-listen-limit= limit the number of outstanding requests
--tls-keep-alive= sets the TCP keep-alive timeouts on accepted connections. It prunes dead TCP connections ( e.g. closing laptop mid-download)
--tls-read-timeout= maximum duration before timing out read of the request
--tls-write-timeout= maximum duration before timing out write of the response
--uid user id value to set on start
--gid group id value to set on start
HAProxy options:
-c, --config-file= Path to the haproxy configuration file (default: /etc/haproxy/haproxy.cfg)
-u, --userlist= Userlist in HAProxy configuration to use for API Basic Authentication (default: controller)
-b, --haproxy-bin= Path to the haproxy binary file (default: haproxy)
-d, --reload-delay= Minimum delay between two reloads (in s) (default: 5)
-r, --reload-cmd= Reload command
-s, --restart-cmd= Restart command
--reload-retention= Reload retention in days, every older reload id will be deleted (default: 1)
-t, --transaction-dir= Path to the transaction directory (default: /tmp/haproxy)
-n, --backups-number= Number of backup configuration files you want to keep, stored in the config dir with version number suffix (default: 0)
--backups-dir= Path to directory in which to place backup files
-m, --master-runtime= Path to the master Runtime API socket
-i, --show-system-info Show system info on info endpoint
-f= Path to the dataplane configuration file (default: /etc/haproxy/dataplaneapi.yaml)
--userlist-file= Path to the dataplaneapi userlist file. By default userlist is read from HAProxy conf. When specified userlist would be read from this file
--fid= Path to file that will dataplaneapi use to write its id (not a pid) that was given to him after joining a cluster
-p, --maps-dir= Path to directory of map files managed by dataplane (default: /etc/haproxy/maps)
--ssl-certs-dir= Path to SSL certificates directory (default: /etc/haproxy/ssl)
--update-map-files Flag used for syncing map files with runtime maps values
--update-map-files-period= Elapsed time in seconds between two maps syncing operations (default: 10)
--cluster-tls-dir= Path where cluster tls certificates will be stored. Defaults to same directory as dataplane configuration file
--spoe-dir= Path to SPOE directory. (default: /etc/haproxy/spoe)
--spoe-transaction-dir= Path to the SPOE transaction directory (default: /tmp/spoe-haproxy)
--master-worker-mode Flag to enable helpers when running within HAProxy
--max-open-transactions= Limit for active transaction in pending state (default: 20)
--validate-cmd= Executes a custom command to perform the HAProxy configuration check
--disable-inotify Disables inotify watcher watcher for the configuration file
--pid-file= Path to file that will dataplaneapi use to write its pid
--debug-socket-path= Unix socket path for the debugging command socket
Logging options:
--log-to=[stdout|file|syslog] Log target, can be stdout, file, or syslog (default: stdout)
--log-file= Location of the log file (default: /var/log/dataplaneapi/dataplaneapi.log)
--log-level=[trace|debug|info|warning|error] Logging level (default: warning)
--log-format=[text|JSON] Logging format (default: text)
--apache-common-log-format= Apache Common Log Format to format the access log entries (default: %h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-agent}i" %{us}T)
Syslog options:
--syslog-address= Syslog address (with port declaration in case of TCP type) where logs should be forwarded: accepting socket path in case of unix or unixgram
--syslog-protocol=[tcp|tcp4|tcp6|unix|unixgram] Syslog server protocol (default: tcp)
--syslog-tag= String to tag the syslog messages (default: dataplaneapi)
--syslog-level= Define the required syslog messages level, allowed values: debug|info|notice|warning|error|critical|alert|emergency (default: debug)
--syslog-facility= Define the Syslog facility number, allowed values: kern|user|mail|daemon|auth|syslog|lpr|news|uucp|cron|authpriv|ftp|local0|local1|local2|local3|local4|local5|local6|local7

Show version:
-v, --version Version and build information
Help Options:
-h, --help Show this help message除了这些选项之外，所有内容都可以在配置文件中定义。查看配置文件
您可以通过简单地运行来测试它：
./dataplaneapi --port 5555 -b /usr/sbin/haproxy -c /etc/haproxy/haproxy.cfg -d 5 -r "service haproxy reload" -s "service haproxy restart" -u dataplaneapi -t /tmp/haproxy
Dataplaneapi 将需要对 haproxy 配置文件和包含其他托管文件（maps、ssl、spoe）的目录的写入权限。可以使用命令行选项覆盖默认位置。使用curl进行测试，请注意，您需要在haproxy配置中的HAProxy用户列表中设置用户/密码组合（在上面的示例中：/etc/haproxy/haproxy.cfg，用户列表控制器）：
curl -u: -H "Content-Type: application/json" "http://127.0.0.1:5555/v2/"
如果您使用安全密码，支持的算法有：md5、sha-256 和 sha-512。
