用脚本抢鸡成功

@zxcvb #17 claude写的，不知道有没有问题。

#!/usr/bin/env bash
set -uo pipefail

读取配置

source "$(dirname "$0")/grab.conf"

OCI="/home/ubuntu/bin/oci"
LOG="$(dirname "$0")/grab.log"

log(){ echo "[$(date '+%F %T')] $*" | tee -a "$LOG"; }

tg(){ # 发 Telegram 通知，失败不影响主流程
curl -s --max-time 15 "$TG_BASE"
--data-urlencode "chat_id=${TG_CHAT_ID}"
--data-urlencode "text=$1" >/dev/null 2>&1 || true
}

刹车二（前置）：已有 cpp 实例就别再抢

exists(){
$OCI compute instance list
--compartment-id "$COMPARTMENT_ID"
--lifecycle-state RUNNING
--query "data[?"display-name"=='${INSTANCE_NAME}'] | length(@)"
--raw-output 2>/dev/null
}

log "===== 抢机启动：${INSTANCE_NAME} ${OCPU}C${MEM_GB}G @ ${AD} ====="
tg "🚀 抢机启动：${INSTANCE_NAME} ${OCPU}C/${MEM_GB}G，开始尝试。"

for ((i=1; i<=MAX_TRIES; i++)); do

刹车二

cnt=$(exists)
if [[ "$cnt" =~ ^[0-9]+$ ]] && (( cnt > 0 )); then
log "检测到已存在 RUNNING 的 ${INSTANCE_NAME}，停止。"
tg "✅ 已存在实例 ${INSTANCE_NAME}，脚本停止（防重复）。"
exit 0
fi

log "第 ${i}/${MAX_TRIES} 次尝试创建…"
OUT=$($OCI compute instance launch

--availability-domain "$AD"
--shape "VM.Standard.A1.Flex"
--shape-config "{"ocpus"😒{OCPU},"memoryInGBs"😒{MEM_GB}}"

--boot-volume-size-in-gbs "$BOOT_GB"
--metadata "{"ssh_authorized_keys":"${SSH_PUBKEY}"}"
2>&1)
RC=$?

if (( RC == 0 )); then
# 刹车一：成功即停
OCID=$(echo "$OUT" | grep -o 'ocid1.instance[^"]*' | head -1)
log "🎉 创建成功！OCID=${OCID}"
tg "🎉 抢到了！${INSTANCE_NAME} ${OCPU}C/${MEM_GB}G 创建成功（第 ${i} 次）。去控制台看公网 IP。"
exit 0

if echo "$OUT" | grep -qi "Out of host capacity"; then
log "容量不足，等待重试。"
else
# 非容量错误：立即停，别傻抢
log "❌ 非容量错误，停止：$OUT"
tg "⚠️ 抢机遇到非容量错误已停止，请查日志：$(echo "$OUT" | head -c 300)"
exit 1
fi

sleep $(( SLEEP_BASE + RANDOM % 21 )) # 60s + 0~20s 抖动
