Multi-Buildpack

建立 .buildpacks 檔案並指定不同的 buildpack

例如:

2
https://github.com/heroku/heroku-buildpack-nodejs
https://github.com/heroku/heroku-buildpack-php

Example

SSH 進 docker container

1
sudo docker exec -i -t <id> bash

Clean up docker

Kill all running containers

1
sudo docker kill $(sudo docker ps -q)

Delete all stopped containers (including data-only containers)

1
sudo docker rm $(sudo docker ps -a -q)

Delete all ‘untagged/dangling’ () images

1
sudo docker rmi $(sudo docker images -q -f dangling=true)

Delete ALL images

1
sudo docker rmi -f $(sudo docker images -q)

已知問題

若與 CSF firewall 搭配使用，重開機後會造成 deployment building 失敗，應該是因為阻擋了 forward 的通道…

所以改用 ufw 代替，需修改 /etc/default/ufw 檔案

將 DEFAULT_FORWARD_POLICY 設為 ACCEPT
