I have installed docker on Ubuntu-21.04 and I'm trying to run apache/nifi on it. I am using this command: docker run --name nifi -dp 8443:8443 apache/nifi. From the logs all seems fine:
Generated Username [24a06eea-579f-443a-ad81-b9fe95d46bd3]
Generated Password [9D3NKqhLElChcXHw0jzfO/wkT8yOV+uV]
2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started. The UI is available at the following URLs:
2022-03-24 15:39:27,726 INFO [main] org.apache.nifi.web.server.JettyServer https://a8917820086b:8443/nifi
The entire logs are here
But if i go at localhost:8443 I see this:
on firefox
and on chrome.
I don't know why I can't access to the UI of Nifi.
I have done all of this exactly on windows 10 and it works. Someone can help me? Thanks in advance.
You need to go to https://localhost:8443 not http://localhost:8443. By default NiFi is now secured with TLS, but 8443 is not the standard HTTPS port, thus it does not automatically redirect you to HTTPS if you only enter localhost

I'm attempting to get a docker registry v2 set up including token auth using self signed certificates.
I can get my docker client to trust the docker registry (by adding the ca.crt into /etc/docker/certs.d/registry.example.com/ in boot2docker)
I'm not sure how to tell the docker registry v2 to trust the auth server, though. I get the following error:
FATA[0003] Error pushing to registry: Get
https://docker-auth.example.com/auth?
scope=repository%3Atest%3Apull%2Cpush&service=registry.example.com:
x509: certificate signed by unknown authority
I'm using the docker auth server here: https://github.com/brandnetworks/docker_auth

I have a nodejs client that uses bramqp for connecting to RabbitMQ server. My client can connect to a Rabbit MQ server in localhost and works well. But it's unable to connect to a remote RabbitMQ server on other machine. I opened port 5672 in the remote server, so I think that the problem is in the configuration of rabbitMQ server. How can I solve this problem?
The problem seems the new rabbitmq access control policy
Please read this post:
Can't access RabbitMQ web management interface after fresh install

while Am trying to use following command
telnet localhost 11211
am getting this error
Connecting To localhost...Could not open connection to the host, on port 11211:
Connect failed
I enabled telnet.How can i overcome this error?
You should check your firewall settings (iptables --list as root or sudo for Linux), and see if there's anything possible blocking that. Check which ports are open (netstat -nl --inet) and also check running processes and find the process that you expect to be listening.
Whatever you expect to be listening on that port is probably not running, or is misconfigured.
