K\u00e4llkoden f\u00f6r projektet Kubegres har publicerats, avsedd f\u00f6r att skapa en kluster av replikerade servrar med databashanteringssystemet PostgreSQL, distribuerat i containerbaserad isoleringsinfrastruktur med plattformen Kubernetes. Paketet g\u00f6r det ocks\u00e5 m\u00f6jligt att hantera datareplication mellan servrar, skapa redundanta konfigurationer och organisera s\u00e4kerhetskopiering. Projektkoden \u00e4r skriven i spr\u00e5ket Go och distribueras under Apache 2.0-licensen. <\/p>\n

Den skapade klustret best\u00e5r av en prim\u00e4r pod-nod av PostgreSQL och sekund\u00e4ra pod-noder som replikerar i realtid, synkroniserade med den prim\u00e4ra noden. Vid ett fel p\u00e5 den prim\u00e4ra noden v\u00e4xlar systemet automatiskt en av de sekund\u00e4ra noderna till prim\u00e4r och \u00e4ndrar konfigurationen f\u00f6r replikationen utan att stoppa arbetet. Det finns m\u00f6jlighet att konfigurera regelbundna s\u00e4kerhetskopior av databasen till en separat lagring. Klusterkonfigurationen anges i YAML-format. Nodernas komponenter skapas baserat p\u00e5 den officiella containern med PostgreSQL som tillhandah\u00e5lls av Docker-projektet. Systemets funktion har bed\u00f6mts som stabil och anv\u00e4nds redan i industriella implementationer.
