EC2 用户数据代码提交克隆失败

Question

我正在从用户数据启动一个 ec2 实例，我需要用我的 ansible 剧本克隆一个存储库，但它无法克隆。详情见下文。谁能帮我弄清楚这一点。当我在引导后通过 ssh 连接到实例时，克隆可以工作，但在引导时不起作用。

#!/usr/bin/env bash
set -x
exec > >(tee /var/log/user-data.log|logger -t user-data -s 2>/dev/console) 2>&1
cd /home/ec2-user
mkdir -p .ssh
ssh-keygen -b 2048 -t rsa -f /home/ec2-user/.ssh/codecommit -q -N ""
KEY_ID=`aws iam  upload-ssh-public-key --user-name ${user_id} --ssh-public-key-body "$(cat /home/ec2-user/.ssh/codecommit.pub)" 
--query 'SSHPublicKey.SSHPublicKeyId' --output text`
echo -e "
Host git-codecommit.*.amazonaws.com
User $KEY_ID
IdentityFile /home/ec2-user/.ssh/codecommit
" >> /home/ec2-user/.ssh/config
ssh-keyscan -t rsa git-codecommit.us-east-2.amazonaws.com >> /home/ec2-user/.ssh/known_hosts
sudo chown -R ec2-user:ec2-user /home/ec2-user/.ssh
sudo chmod 700 /home/ec2-user/.ssh
sudo chmod 644 /home/ec2-user/.ssh/*
sudo chmod 600 /home/ec2-user/.ssh/codecommit*
eval "$(ssh-agent -s)"
export GIT_SSH_COMMAND="ssh -v -F /home/ec2-user/.ssh/config -o StrictHostKeyChecking=no"
export GIT_TRACE_PACKET=true
export GIT_TRACE=2
export GIT_CURL_VERBOSE=1
**sleep 60s**
git clone ssh://git-codecommit.us-east-2.amazonaws.com/v1/repos/ansible

在 git clone 命令之前添加 60 秒的睡眠就可以了。SSH密钥上传似乎需要一些时间才能激活。

sleep 60s
git clone ssh://git-codecommit.us-east-2.amazonaws.com/v1/repos/ansible

或

for i in {1..30}; do
git clone ssh://git-codecommit.us-east-2.amazonaws.com/v1/repos/ansible      
[ $? == 0 ] && break || sleep 2s; echo "keep trying ..."
done
