I am using Microk8s on my local Windows 10 machine and am unable to get pods or use most of kubectl commands.
At the time of installation of microk8s, multipass selected VitrualBox for VM virtualization.
I get below error
C:\Users\owner>microk8s kubectl get pods
Unable to connect to the server: dial tcp 10.0.2.15:16443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
VirtualBox Version 6.1
Ensured that multipass list shows that the VM is in running state.
There was a prior version of VitrualBox and minikube - both of which I have now un-installed and installed VirtualBox alone. Also cleaned up %USER_HOME%/.kube directory and %USER_HOME%/AppData/local/minikube & %USER_HOME%/AppData/local/VirtualBox folders too.

I am following these instructions to deploy a Django app on Google App Engine:
https://cloud.google.com/python/django/appengine
I have got as far as downloading the proxy .exe file (I am on a Windows machine) and connecting to it:
2019/01/08 16:14:08 Listening on 127.0.0.1:3306 for
[INSTANCE-NAME] 2019/01/08 16:14:08
Ready for new connections
When I try and create the Django migrations by running python manage.py createmigrations I see the connection received by the proxy file:
2019/01/08 16:15:06 New connection for
"[INSTANCE-NAME]"
However, after a couple of seconds pause I get this error:
2019/01/08 16:15:28 couldn't connect to
"[INSTANCE-NAME]": dial tcp
35.205.185.133:3307: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
I have tried disabling my local firewall in case this was causing any issues, but the result is the same. I've also checked the username, password and Cloud SQL instance name, they are all correct.
What could be causing this error?
I was able to successfully deploy BOSH and CF on GCP. I was able to install the cf cli on my worker machine and was able to cf login to the api endpoint without any issues. Now I am attempting to deploy a python and a node.js hello-world style application (cf push) but I am running into the following error:
Python:

I am able to download and ping the build pack urls manually on the worker machine, jumpbox, and the bosh vms so I believe DNS is working properly on each of those machine types.
As part of the default deployment, I believe a socks5 tunnel is created to allow communication from my worker machine to the jumpbox so this is where I believe the issue lies. https://docs.cloudfoundry.org/cf-cli/http-proxy.html
When running bbl print-env, export BOSH_ALL_PROXY=ssh+socks5://jumpbox#35.192.140.0:22?private-key=/tmp/bosh-jumpbox725514160/bosh_jumpbox_private.key , however when I export https_proxy=socks5://jumpbox#35.192.140.0:22?private-key=/tmp/bosh-jumpbox389236516/bosh_jumpbox_private.key and do a cf push I receive the following error:
Request error: Get https://api.cloudfoundry.costub.com/v2/info: proxy: SOCKS5 proxy at 35.192.140.0:22 has unexpected version 83
TIP: If you are behind a firewall and require an HTTP proxy, verify the https_proxy environment variable is correctly set. Else, check your network connection.
FAILED
Am I on the right track? Is my https_proxy variable formatted correctly? I also tried https_proxy=socks5://jumpbox#35.192.140.0:22 with the same result.
I have installed the latest versions of Virtualbox v.5.2.6 and Vagrant v.2.0.1 on the windows machine with the Intel-Core-i5-4210U-Processor #1.70Ghz 2.40Ghz. I have added the homestead box by running the command:
vagrant box add laravel/homestead
But, on running the vagrant up it runs fine until this point:
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within the
configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that Vagrant
had when attempting to connect to the machine. These errors are
usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes. Verify
that authentication configurations are also setup properly, as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
On running the vagrant ssh-config I get:
Host homestead-7
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile C:/Users/MyUser/.vagrant.d/insecure_private_key
IdentitiesOnly yes
LogLevel FATAL
ForwardAgent yes
I have looked around and tried out different things, among others, to uninstall and install again both vagrant and virtualbox, but couldn't find any solution. How can I get this working?
I made VM Ubuntu 16.04 with one network adapter "network bridge" and second adapter "internal network". ClickHouse DBMS installed by default.
Test call within slave Ubuntu curl 'http://localhost:8123/' returns Ok.
But the same call from master Windows host returns nothing :(
Telnet and browser from master OS on http://assignedIP:8123 returns ERR_CONNECTION_REFUSED.
At the same time pings slave Ubintu from master OS and opposite are successful.
How to setup VM's network properly to be able to call ClickHouse on port 8123 from master OS?
Found it!
Have to change
<listen_host>::1</listen_host>
to
<listen_host>::</listen_host>
in /etc/clickhouse-server/config.xml
Could you please check Unbutu firewall status. If it is up, bring it down and try.
I am trying to get Django-Celery running on my Django App. I cannot get the worker server to run. When I try I get the message: No Connection could be made because the target machine actively refused it
Here is what I have done so far. First, I installed the django celery package: http://pypi.python.org/pypi/django-celery
I can load it into python without problems. I also installed the RabbitMQ server per the windows install instructions: http://www.rabbitmq.com/install.html#windows
Starting the tutorials in pytho on the RabbitMQ site I saw the need to install pika: http://pypi.python.org/pypi/pika. It imports without any problems.
From there I start the RabbitMQ server by running this at the command line: rabbitmq-service start
I get the message back that Service RabbitMQ started
Here is where I start to have problems.
I attempted the first steps in django-celery: http://packages.python.org/django-celery/getting-started/first-steps-with-django.html and the "hello world" example on the rabbitMQ site: http://www.rabbitmq.com/tutorials/tutorial-one-python.html
In both cases I get the message: No Connection could be made because the target machine actively refused it
My first thought was that this sounded like a firewall problem. So I went into the windows 7 firewall and added inbound and outbound rules to open the local and remote ports 5672 and 5673 to TCP protocol, but I still get the same error message.
When I run rabbitmqctl status i get the message:
Error: unable to connect to node 'rabbit#hostname': nodedown
diagnostics:
- nodes and their ports on hostname: [{rabbitmqctl18856, 505031}]
Does that mean it that it is trying to operate on those ports? what about the default 5672?
Any suggestions?
UPDATE: This was actually a problem resulting from several failed rabbitmq installs conflicting with the latest installation. If you have to remove rabbitmq use the 'rabbitmq-service remove' command and not SC DELETE, which cause a lot of problems for me and I had to go in and clean up my windows registry file.
The nodedown error indicated by rabbitmqctl suggests that the server isn't running on that machine.
Try going though the steps in RabbitMQ's troubleshooting guide. In particular, pay close attention to the logs. Has the server crashed for some reason? Could you post the logs somewhere?
