Data Plane API adalah proses sespan yang berjalan di samping HAProxy dan menyediakan titik akhir API untuk mengelola HAProxy. Ini memerlukan HAProxy versi 1.9.0 atau lebih tinggi.
Untuk membangun Data Plane API, Anda perlu menginstal Go di sistem Anda dengan dukungan modul go diaktifkan, dan menjalankan langkah-langkah berikut:
1. Kloning repositori dataplaneapi
git clone https://github.com/haproxytech/dataplaneapi.git
2. Jalankan pembuatan build:
make build
3. Anda dapat menemukan biner bawaan di direktori /build. TES
Penggunaan dasar:
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) --max-header-size= controls the maximum number of bytes the server will read parsing the request header's keys and values, including the request line. It does not limit the size of the request body. (default: 1MiB) --socket-path= the unix socket to listen on (default: /var/run/data-plane.sock) --host= the IP to listen on (default: localhost) [$HOST] --port= the port to listen on for insecure connections, defaults to a random value [$PORT] --listen-limit= limit the number of outstanding requests --keep-alive= sets the TCP keep-alive timeouts on accepted connections. It prunes dead TCP connections ( e.g. closing laptop mid-download) (default: 3m) --read-timeout= maximum duration before timing out read of the request (default: 30s) --write-timeout= maximum duration before timing out write of the response (default: 60s) --tls-host= the IP to listen on for tls, when not specified it's the same as --host [$TLS_HOST] --tls-port= the port to listen on for secure connections, defaults to a random value [$TLS_PORT] --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 (default: local0) Show version: -v, --version Version and build information Help Options: -h, --help Show this help message
Selain opsi tersebut, semuanya dapat ditentukan di sisi file konfigurasi. Lihat file konfigurasi
Anda dapat mengujinya hanya dengan menjalankan:
./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 akan memerlukan izin menulis ke file konfigurasi haproxy dan direktori yang berisi file terkelola tambahan (peta, ssl, spoe). Lokasi default dapat diganti dengan opsi baris perintah. Uji dengan curl, perhatikan bahwa Anda memerlukan pengaturan kombinasi pengguna/pass di daftar pengguna HAProxy dalam konfigurasi haproxy (dalam contoh di atas: /etc/haproxy/haproxy.cfg, pengontrol daftar pengguna):
curl -u: -H "Content-Type: application/json" "http://127.0.0.1:5555/v2/"
Jika Anda menggunakan kata sandi yang aman, algoritma yang didukung adalah: md5, sha-256 dan sha-512.

Alternatifnya, dataplaneapi menyajikan dokumentasi interaktifnya sendiri yang relevan untuk build saat ini di uri /v2/docs
. Cukup arahkan browser Anda ke host/port dataplane tempat dimulainya (yaitu http://localhost:5555/v2/docs
)
