1.3. 为旧 HTTPS 证书扫描 RHOSP 端点

流程

1. 将以下脚本保存到机器中：

   #!/usr/bin/env bash
   
   set -Eeuo pipefail
   
   declare catalog san
   catalog="$(mktemp)"
   san="$(mktemp)"
   readonly catalog san
   
   declare invalid=0
   
   openstack catalog list --format json --column Name --column Endpoints \
   	| jq -r '.[] | .Name as $name | .Endpoints[] | select(.interface=="public") | [$name, .interface, .url] | join(" ")' \
   	| sort \
   	> "$catalog"
   
   while read -r name interface url; do
   	# Ignore HTTP
   	if [[ ${url#"http://"} != "$url" ]]; then
   		continue
   	fi
   
   	# Remove the schema from the URL
   	noschema=${url#"https://"}
   
   	# If the schema was not HTTPS, error
   	if [[ "$noschema" == "$url" ]]; then
   		echo "ERROR (unknown schema): $name $interface $url"
   		exit 2
   	fi
   
   	# Remove the path and only keep host and port
   	noschema="${noschema%%/*}"
   	host="${noschema%%:*}"
   	port="${noschema##*:}"
   
   	# Add the port if was implicit
   	if [[ "$port" == "$host" ]]; then
   		port='443'
   	fi
   
   	# Get the SAN fields
   	openssl s_client -showcerts -servername "$host" -connect "$host:$port" </dev/null 2>/dev/null \
   		| openssl x509 -noout -ext subjectAltName \
   		> "$san"
   
   	# openssl returns the empty string if no SAN is found.
   	# If a SAN is found, openssl is expected to return something like:
   	#
   	#    X509v3 Subject Alternative Name:
   	#        DNS:standalone, DNS:osp1, IP Address:192.168.2.1, IP Address:10.254.1.2
   	if [[ "$(grep -c "Subject Alternative Name" "$san" || true)" -gt 0 ]]; then
   		echo "PASS: $name $interface $url"
   	else
   		invalid=$((invalid+1))
   		echo "INVALID: $name $interface $url"
   	fi
   done < "$catalog"
   
   # clean up temporary files
   rm "$catalog" "$san"
   
   if [[ $invalid -gt 0 ]]; then
   	echo "${invalid} legacy certificates were detected. Update your certificates to include a SAN field."
   	exit 1
   else
   	echo "All HTTPS certificates for this cloud are valid."
   fi

2. 运行脚本。
3. 将脚本报告为 INVALID 的任何证书替换为包含 SAN 字段的证书。
