nifi@container_id:/opt/nifi/nifi-current$ echo "java.arg.8=-Duser.timezone=America/Sao_Paulo" >> conf/bootstrap.conf
nifi@container_id:/opt/nifi/nifi-current$ cd lib
nifi@container_id:/opt/nifi/nifi-current/lib$ wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.29/mysql-connector-java-8.0.29.jar
nifi@container_id:/opt/nifi/nifi-current/lib$ wget https://repo1.maven.org/maven2/com/oracle/database/jdbc/ojdbc8/21.5.0.0/ojdbc8-21.5.0.0.jar
nifi@container_id:/opt/nifi/nifi-current/lib$ wget https://repo1.maven.org/maven2/org/postgresql/postgresql/42.4.0/postgresql-42.4.0.jar
nifi@container_id:/opt/nifi/nifi-current/lib$ wget https://repo1.maven.org/maven2/org/apache/nifi/nifi-kite-nar/1.15.3/nifi-kite-nar-1.15.3.nar

nifi@container_id:/opt/nifi/nifi-current$ ./bin/nifi.sh stop

Restart you container

$ docker start nifi

Update the restart policy

$ docker update --restart=always nifi

Read current restart policy

docker inspect -f "{{ .HostConfig.RestartPolicy }}" nifi

4. Access Nifi Web Service

Now you can access your Nifi web service at http://localhost:8080/nifi/

If you are in a VPN environment remember to tunnel 8080 port

$ ssh -f user@ip_address -L 8080:localhost:8080 -N
