+- Create a CSR file
+```bash
+./gen_domain_cert.py --domain-id=dss --out=csr --O=Axway --OU=DSS --C=US --ST=AZ --L=Scottsdale --pass-file=rootcerts/pass.txt
+```
+command creates a folder named dss under apigw-emt-scripts-2.1.0-SNAPSHOT/certs/ with following files
+
+    - dss.csr
+    - dss-key.pem
+
+- Create CA CSR, certificate and key
+```bash
+openssl genrsa -aes256 -out CA.key 2048
+openssl req -new -sha256 -key CA.key -out CA.csr -subj "/C=US/ST=AZ/L=Scottsdale/O=AXWAY/CN=CACERTIFICATE"
+openssl x509 -signkey CA.key -in CA.csr -req -days 3650 -out CA.pem
+```
+command creates following files
+
+    - CA.key
+    - CA.csr
+    - CA.pem
+    - CA.srl
+
+- Create a file openssl.cnf with following content

+- Sign dss.csr with CA certificate and key using openssl configuration 
+
+```bash
+openssl x509 -req -days 360 -in dss.csr -CA CA.pem -CAkey CA.key -CAcreateserial -out signedbyCA.crt -sha256 -extensions admin_node_manager_extensions -extfile openssl.cnf
+```
+
+- Create a P12 file from CA signed certificate and key file
+
+```bash
+openssl pkcs12 -export -in signedbyCA.crt -inkey dss-key.pem -out domain.p12 -chain -CAfile CA.pem -name 'topology-cert'
+```
+**alias name should be 'topology-cert'**
+
+- Prepare Admin Node Manager fed file
+
+    - Export Admin Node manager fed from classic installation, remove existing topology-cert and change remove / rename port name without blank space (e.g sslport)
+
+    - Import loadable module
+  Policystudio using File -> Import -> Import Custom filters -> select apim-policy-password-cert-env/src/main/resources/typeSet.xml.
+
+    - Export fed file
+
+- Configure environment variable (docker-compose / kubernetes deployment)
+
+```yaml
+ # docker-compose.yaml example
+ environment:
+      EMT_TOPOLOGY_LOG_ENABLED: 'true'
+      EMT_TOPOLOGY_LOG_DEST: 3
+      certandkey_sslport: /opt/Axway/apigateway/domain.p12
+      certandkeypassword_sslport: changeme
+      certandkeymtls_sslport: 'true'
+```
+    
+- comment lines related to certificate generation in apigw-emt-scripts-2.1.0-SNAPSHOT/Dockerfiles/emt-nodemanager/scripts/setup_emt_nodemanager.py
+```python

+
+        except Exception, e:

+
+```bash
+./build_anm_image.py --default-cert --default-user --parent-image=apigw-base --merge-dir=/Users/rnatarajan/APIM/apigw-emt-scripts-2.1.0-SNAPSHOT/apigateway --fed extanm.fed --out-image=admin-node-manager-ext-ca-env:latest

+
+```bash
+dssgateway$cp ../dss/CA.pem .
+dssgateway$cp ../dss/CA.key .
+dssgateway$cp ../dss/CA.srl .
