game design

	好的，我來將我剛剛設計的桌遊概念用中文詳細解釋一遍。這個遊戲的核心概念是結合了商業經營、策略規劃、風險管理，以及一些玩家互動的元素。

	首先，我需要將遊戲的整體畫面呈現出來。想像一個熱鬧的火車站旁邊，有一條主要的街道，街道上有許多可以蓋建築的地點。玩家扮演不同的店家，可以購買這些地塊，然後蓋自己的商店。火車站是人潮的來源，特別是在天氣好的時候。地塊的位置很重要，越靠近車站的地塊越貴，但同時也更有優勢。遊戲中還有一些共享的資源，像是天氣效果，還有一些玩家會競爭的設施。

	這個遊戲圍繞幾個核心的循環。玩家買地，蓋商店，吸引顧客。他們要管理金錢，升級建築，還可以陷害對手，同時應對多變的天氣。天氣系統增加了一些不確定性，也需要玩家投資在共同的基礎設施上。最靠近車站的地塊有優先選擇客人的權利，這增加了競爭的層面。

	現在，我們來看看具體的遊戲機制。建築物要從一樓開始蓋，這增加了一種進展感。天氣系統會影響顧客的數量（晴天人多、雨天可能損壞、颱風停電），玩家可以選擇蓋避雷針來減少損失，但這樣就不能再往上蓋了。發電機和停車場則只能蓋在地下室，這讓玩家需要考慮是要優先衝高樓層還是蓋設施。

	不同的商店和設施也增加了遊戲的深度。某些商店會有最適合的地點，像是便利商店適合在一樓，離車站近一點。停車場和發電機放在地下室是很合理的安排，而且它們看起來會是玩家需要的設施，玩家必須在這些基礎設施和純粹的盈利之間做選擇。

	ifconfig (or ip link, ip addr) - for obtaining information about network interfaces

	ping

	for validating, if target host is accessible from my machine.

	ping is also could be used for basic DNS diagnostics - we could ping host by IP-address or by its hostname and then decide if DNS works at all. And then traceroute or tracepath or mtr to look what's going on on the way there.

Using environment variables in Kubernetes deployment spec

	https://serverfault.com/questions/791715/using-environment-variables-in-kubernetes-deployment-spec

	A much easier/cleaner solution: envsubst

	In deploy.yml:

	LoadbalancerIP: $LBIP
	Then just create your env var and run kubectl like this:

	export LBIP="1.2.3.4"
