ルート CA と下位 CA を異なる AWS アカウントで作成

[アカウントA] ルート CA を作成

config=$(cat <<EOM

    "KeyAlgorithm":"RSA_2048",
    "SigningAlgorithm":"SHA256WITHRSA",
    "Subject":{
       "Country":"US",

       "OrganizationalUnit":"Sales",
       "State":"WA",
       "Locality":"Seattle",
       "CommonName":"www.example.com"
    }
 }
EOM

aws acm-pca create-certificate-authority \
--certificate-authority-configuration "$config" \
--certificate-authority-type "ROOT" \
--usage-mode GENERAL_PURPOSE \
--region us-east-1

出力
