| (key: http://go/go-builders-ssh) |
| |
| Machine setup: |
| |
| * start with Ubuntu bionic |
| * install docker-ce from Docker |
| * GOOS=linux GOARCH=arm go install golang.org/x/build/cmd/rundockerbuildlet |
| * scp -C -i ~/keys/id_ed25519_golang1 $(GOOS=linux GOARCH=arm go list -f {{.Target}} golang.org/x/build/cmd/rundockerbuildlet) root@$C1_SERVER_IP:/usr/local/bin |
| * scp -i ~/keys/id_ed25519_golang1 rundockerbuildlet.service root@$C1_SERVER_IP:/etc/systemd/user/ |
| * ssh -i ~/keys/id_ed25519_golang1 root@$C1_SERVER_IP systemctl enable /etc/systemd/user/rundockerbuildlet.service |
| * ssh -i ~/keys/id_ed25519_golang1 root@$C1_SERVER_IP systemctl start rundockerbuildlet |
| |
| * stop it |
| * snapshot its attached volume, name it (e.g. "buildlet-2019-11-05-1"), note its UUID |
| * click "Images" in top tab, create an image from that same snapshot. Can use the same name. (different namespaces) |
| * click "..." and "More info" on that image, get its ID (e.g. "13f4c905-3a4b-475a-aaba-a13168e2b6c7") |
| * copy that to cmd/scaleway's default flag value |
| * also update cmd/scaleway's bootscript value, if needed: |
| |
| First, find out which bootscript (netboot kernel, initrd, etc) that the original image was using: |

| |
| Updating the docker image on eu.gcr.io: |
| |
| * create a dev Ubuntu image on scaleway |
| * install Docker on it |
| * copy Dockerfile to it |
| |
| root@scaleway:~# cat Dockerfile | docker build -t eu.gcr.io/symbolic-datum-552/scaleway-builder - |
| |
| * in your normal gcloud dev environment, get a short-lived access token: |
| |
| you@dev:~$ gcloud auth print-access-token |
| |
| * copy/paste it |
| * back on scaleway, log in, and paste the token when it asks for the password: |
| |
| root@scaleway:~# docker login -u oauth2accesstoken https://eu.gcr.io |
| Password: <paste> |
| WARNING! Your password will be stored unencrypted in /root/.docker/config.json. |
| |
| root@scaleway:~# docker push eu.gcr.io/symbolic-datum-552/scaleway-builder |
