O Arachne rodava 10 serviços em Docker Compose. Kubernetes aparecia no meu CV como keyword desejada — mas eu não usava. Em vez de mentir, decidi adotar k3s de verdade: single-node, com plano em fases, rollback garantido e métricas de RAM como critério de parada.
Arachne ran 10 services on Docker Compose. Kubernetes showed up on my resume as a desired keyword — but I didn't use it. Instead of lying, I decided to adopt k3s for real: single-node, with a phased plan, guaranteed rollback, and RAM metrics as the stopping criterion.
O hub pessoal devolvia 502 intermitente no tunnel. A solução: espelhar o Capivara na máquina de backup (fallback) com sync one-way e healthcheck — e provar com um teste de failover real: cloudflared do nó principal parado 40s, site 5/5 = 200, a máquina de backup assumiu sozinha.
The personal hub was returning intermittent 502s on the tunnel. The fix: mirror Capivara to the backup machine (fallback) with one-way sync and healthcheck — and prove it with a real failover test: The primary node's cloudflared stopped for 40s, site 5/5 = 200, the backup machine took over by itself.
