我希望在 EC2 实例上安装 CodeDeploy 代理,并通过 CloudFormation 部署用户数据。 Here is the script I'm using from AWS
但是,当我将脚本放置在 CloudFormation 中 EC2 实例的 UserData 属性中时,我从 linter 中收到此错误:
E1019 Parameter PLAT for Fn::Sub not found at Resources/Server/Properties/UserData/Fn::Base64/Fn::Sub
这是片段:
UserData:
'Fn::Base64': !Sub |
#!/bin/bash -xe

function installdep(){
if [ ${PLAT} = "ubuntu" ]; then
apt-get -y update
# Satisfying even ubuntu older versions.
apt-get -y install jq awscli ruby2.0 || apt-get -y install jq awscli ruby
elif [ ${PLAT} = "amz" ]; then
yum -y update
yum install -y aws-cli ruby jq
fi
}
function platformize(){
#Linux OS detection#
if hash lsb_release; then
echo "Ubuntu server OS detected"
export PLAT="ubuntu"
elif hash yum; then
echo "Amazon Linux detected"
export PLAT="amz"
else
echo "Unsupported release"
exit 1
fi
}
function execute(){
if [ ${PLAT} = "ubuntu" ]; then
cd /tmp/
wget https://aws-codedeploy-${REGION}.s3.amazonaws.com/latest/install
chmod +x ./install
if ./install auto; then
echo "Instalation completed"
if ! ${AUTOUPDATE}; then
echo "Disabling Auto Update"
sed -i '/@reboot/d' /etc/cron.d/codedeploy-agent-update
chattr +i /etc/cron.d/codedeploy-agent-update
rm -f /tmp/install

exit 0

我在这里缺少什么?当使用通过控制台创建实例时,此脚本在用户数据中运行良好。提前致谢!

向@jordanm 的评论致敬。这解决了我的问题。
