I need to automate the detection of the host machine IP during a vagrant up in order to build a config file. Is there an easy way to do this using Saltstack?

I have installed Virtual Box (Version 5.2.0 r118431 (Qt5.6.2)) on Windows 10 and i imported appliance HDP_2.4_virtualbox_v3 (downloaded from here).
I followed the tutorial from here step by step.
The virtual machine is running on the computer from where I am trying to access the Dashboard. I have set up the Host Only Adapter Option on the sandbox so the computer and the virtual machine can communicate
After the CentOs finished booting I am prompt to enter to the ip 127.0.0.1:8888, which is a different address from the tutorial,
and there is no server listening to that address because i get
"127.0.0.1 refused to connect." in the browser.

Run the ipconfig command in your command prompt and identyfy your virtual box's ip under Ethernet adapter VirtualBox Host-Only Network.
Take that ip address and go to your Virtual Box.
Select your appliance and go to Settings->Network->Adapter 1->Port Forwarding.
Replace the Host IP 127.0.0.1 for the port you need 8080, 8888 and so on with the ip of your virtual box that should be sth like 192.168.x.x.
Now start your sandbox, login on it and try to connect in your browser to the new ip set 192.168.x.x:8888.
Use appliance HDP_2.4_virtualbox because in the most recent some linux commands like netstat are considered deprecated and no longer function, which willmake your life harder when trying to debug or identify a networking problem.
If you still encounter issues eith it, reinstall your operating system, reinstall your virtual box and reimport the sandbox, make the changes needed in the Port Forwarding settings and it should be ok.
try to connect using 127.0.0.1 to connect make sure the VM is running make sure there are no errors if there are debug them and at the last straw uninstall the Vm and retry (make sure to make a backup if there are any files)
you can also try to check all the local host ips on your network and try to connect to them
Make sure you set NAT in your VirtualBox network settings:
I have recently learned how to setup a virtual machine using vagrant (virtualbox), and I know how to access it from a web browser via the local adress such as 192.168.x.x:9292 since 9292 is the default gate. But I would like to access the server from another computer locally.
My question is if I could access it via cmd as I connect to it on my own with the command vagrant ssh but from another computer via a command like vagrant ssh 192.168.x.x?
As far as I understand you have to use external programs or setup something inside the vagrant environment? Is there a simple way to access the server or is it password protected? If I setup a website I can access that for example from another local machine but can I access files on the server (from another computer)?
I found how to connect to another computer locally by entering the vagrant environment, vagrant up --> vagrant ssh. And connected to another computer by typing in ssh vagrant#192.168.x.x where 192.168.x.x is the local address to the computer. The vagrant asks for a password and you type in the default password which I believe is vagrant and then you are connected to the other vagrant instance.
Assuming you have virtualbox provider for Vagrant you can achieve this by doing bridging the VBox network interface with Host.
Use this in Vagratfile (for public/private)
For Public
Vagrant.configure("2") do |config|
config.vm.network "public_network",
use_dhcp_assigned_default_route: true
end
For Private
Vagrant.configure("2") do |config|
config.vm.network "private_network", type: "dhcp"
end
above code will create IP in the range of Host network and using this you can access the file server from another machine.
We are trying to use Vagrant to run a Redis server on Mac (using an Ubuntu Guest OS) with this Vagrantfile
Sadly we are unable to access the Redis database inside the Vagrant Box.
We get this error:
Error: Redis connection to 127.0.0.1:6379 failed - read ECONNRESET
This is the Network configuration in the VirtualBox VM:
What else do we need to add to the Vagrantfile to expose Redis to Mac?
(Note: the reason for using Vagrant is both to let people try redis without having to install it on their main OS, but more importantly to ensure that other elements of the app run as expected)
This may be helpful https://serverfault.com/questions/248248/cannot-connect-to-redis-installed-on-virtualbox-running-ubuntu-from-windows-7. I know question is about connecting from Windows, but the solution is mostly modifications to the Redis config within the VM in order to not bind Redis only to a local port in the redis.conf so that it can be accessed on the host machine(Mac in your case).
Also, depending on how you are trying to access Redis you may be able to configure a SSH tunnel on the host machine(Mac) in order to gain access to the Redis server within the Vagrant VM. I ended up going this route for my case to connect to Redis inside of a Vagrant VM for local development of an Ember JS app using ember-cli and ember-cli deploy with ember-cli-deploy-redis
You can give a Private IP to the Vagrant box and then access redis using the private IP.
For example, lets say you want to configure 192.168.33.10 as you Vagrant box IP. Simply add this line in Vagrant file.
Vagrant.configure(2) do |config|
config.vm.network 'private_network', ip: '192.168.33.10'
end
From now u can access your vagrant box using 192.168.33.10
I happen to run Redis within a Docker container in addition to the Vagrant setup. Running into this question again and again, I want to a add my findings.
Indeed making sure binding to net devices is to 0.0.0.0 instead of 127.0.0.1 is essential. Since I am running Docker I just had to make sure the container is properly run:
docker run -d redis -p 0.0.0.0:6379:6379 redis
Then, in addition the known Vagrant configuration:
config.vm.network :forwarded_port, guest: 6379, host: 6379
And voilà: running Redis in a Vagrant VM using Docker, able to access it from the Mac OSX host system.
This is without changing the Redis config, since Docker takes care of this.
I'm trying to copy my public key from a CentOS environment to a Ubuntu machine. I used the following command
ssh-copy-id root#Ubuntu_IP
However I get an error saying Connection timed out. I'm able to ping from my host to the remote machine. The purpose behind this is that my host machine is ansible control node where as Ubuntu machine is my managed node.
Make sure you add a permanent route in the remote machine for the host machine.
route add -net remote_ip netmask mask_ip gw gateway_ip eth0
Also disable the firewall on the remote machine. This seemed to have solved the problem in my case.
I followed the instructions here and was able to succesfully (I think) install the gitlab vagrant virtual machine on OSX 10.8 using virtualbox.
I can do vagrant up to get the VM running, and everything seems to work fine. After that I can do vagrant ssh without a problem. Also, after sshing into the VM I was able to do bundle exec rake gitlab:test, which completed with results being 1584 examples, 0 failures.
I would like to see the gitlab web interface from my OSX host machine. I thought I could just direct my browser to the IP indicated in the VagrantFile (http://192.168.3.14), but that didn't work.
Any ideas?
Also any other usage tips for this setup would be appriciated (things like where the repositories are stored on my host machine so I can back them up, if anyone set the gitlab-vagrant-vm up for external access from either another computer on the network or a remote source, ect.)
You have to connect a second interface for vagrant. To do this you've to edit the VagrantFile.
For example if you want to conenct to the host wifi add the following line after 192.168.3.14
config.vm.network :bridged, bridge: "en0: Wi-Fi (AirPort)"
You also can bridge to the ethernet interface. Use ifconfig on the host machine to determine the right interface. After that the dyndns-server of the host network will assign an IP to the Vagrant-Box. Then you can access GitLab on that IP.
Did you actually start the server? You can do that with
bundle exec foreman start -p 3000
This will start the server on port 3000, you would then access it from the host with
http://192.168.3.14:3000/
Hope this helps,
