Access cluster workload

To access workload services within your cluster, connect allows you to forward these adresses and ports locally and allow easy access.

sudo devkube connect
...
5:58PM INF adding tunnel namespace=platform hosts="[dashboard.platform dashboard.platform.svc.cluster.local]" ports=[80]
5:58PM INF adding tunnel namespace=platform hosts="[grafana.platform grafana.platform.svc.cluster.local]" ports=[80]
...

Import a local image

# pull an image (or build one)
docker pull alpine:3

# import image into cluster registry
devkube load alpine:3

Build an image within cluster

cd /path/to/your/project

# cat Dockerfile
# FROM alpine:3
# RUN apk add --no-cache bash

# build image using buildkitd
devkube build demo .
★ creating container (default/loop-buildkit-704c031)...
★ copying build context...
...
★ removing container (default/loop-buildkit-704c031)..

# run impage in kubernetes
kubectl run -it --rm demo --image registry.platform/demo /bin/bash
demo:/# exit
