Egne værktøjer

Portway Education Ét login til hele skolen: Portway opretter og vedligeholder brugerne i Microsoft 365 eller Google Workspace, og elever og ansatte logger ind dér med deres Unilogin. → portway.dk

Portway Work HR-automation til Google Workspace: onboarding, roller, kalendere og delte drev, styret ét sted. I drift hos første kunde. MCP er indbygget, så AI kan betjene systemet med login, rettigheder og audit-log. → portway.dk/work

Portway LocalBox Lokal site-appliance baseret på Proxmox: internetfilter med kategorier, lokalt fil-share, print og netværksovervågning. Til dem der vil have driften tæt på. Kører hos flere kunder i dag.

Alle tre hører under Portway, produktfamilien jeg samler mine værktøjer under. Work og Education kan du læse mere om på portway.dk. LocalBox sætter jeg op i dialog med den enkelte kunde.

Spørg om

Jeg oversætter nørd til dansk.

Her er et par af de jargon-ord, der dukker op i samtaler. Du behøver ikke kende dem for at arbejde med mig, men hvis du bliver nysgerrig, er det her den korte version.

help --topic docker

Docker er et værktøj der pakker et program ind med alt det skal bruge (biblioteker, indstillinger, dependencies), så det kører ens på din maskine, hos mig, eller på en server hos en kunde. Pakken kaldes et "image"; pakken når den kører kaldes en container.

help --topic container

En container er et program der kører i sin egen lille kasse på en computer. Den deler operativsystem med værten, men ser ikke resten af systemet. Lettere end en virtuel maskine, men stadig isoleret. Docker, LXC og Kubernetes håndterer alle containere — bare på lidt forskellige måder.

help --topic vm

En virtuel maskine er en komplet computer der kører inde i en anden. Egen kerne, egen RAM, egen virtuel harddisk. Tungere end en container, men giver fuld isolation. Du kan fx køre Windows på en Linux-server. Bruges når miljøer skal adskilles fuldstændigt.

help --topic bare-metal

"Bare-metal" betyder direkte på hardwaren, ingen virtualisering imellem. En hypervisor er det der lader flere virtuelle maskiner køre samtidigt på samme fysiske server. Type 1 (Proxmox, ESXi, Hyper-V) kører bare-metal; Type 2 (VirtualBox, Parallels) kører oven på et almindeligt OS.

I mit eget homelab

Det her er hvor jeg leger, så jeg kan komme med svar på onsdag. Det er også grunden til at jeg ved hvad jeg taler om, når jeg anbefaler noget: jeg har som regel selv brændt mig på det først.

// LocalBox er i bund og grund "homelabben i en boks, lavet til at sælges"

Den dag du ringer og spørger "kan vi gøre sådan og sådan?", er det rart at vide at svaret kommer fra en der har prøvet det.

Og så er nogle af jer nysgerrige af samme grund som mig.
