We run tests on Azure Container Instances.
My question is rather simple. Is there a way to assign a public static ip address to the containers?
Our tests are running and need connection to certain nodes, but how to allow them that if I don't know what the public address will be?
If not what else as an option there is?
Unfortunately, it's impossible the assign a static public IP to the Azure Container Instance. Instead, you can create the Container Instance in a VNet, then put the container instance behind an application gateway and assign a static public IP to the application gateway. In this way, you can access the container instance via the static public IP address.

I have created a container instance (the public one)... I am able to access the container using public IP(generated) and using FQDN. But I want to assign a static Public IP which I created using Public IP addresses in azure instead of auto-generated.
Could you help me,
how to assign the static IP to the container instance?
Can I use FQDN (Microsoft) to map to custom DNS record set (Azure)
I was following this article - Azure virtual machine scale set agents. Everything is good and I am able to run my custom images to perform builds and deployments.
One thing that is missing there - what if agent needs to access some IP restricted resource? Previously (with a simple VM running as agent) it was easy to whitelist public IP of a given agent. With those scale sets (and --load-balancer "") I am not sure how to get them to use a static IP (preferably only 1 outgoing public IP for all VMs in a set)
Any suggestions?
When you use a Load Balancer in front of the VMSS with only one static public IP address, then all the VMSS instances only can access outside through that one static public IP address. It's easy to achieve it, you just need to configure the public IP address as static. Then you put that public IP address in the whitelist for the restricted resource.
In this way, all the instances access the restricted resource via the static public IP address and it's in the whitelist.
I want to provision a VM which has no public ip so it can only be connected from other VM who have public ip. Now i can create a VM without public ip but then it does not have a internet access.
Now is there a way on Azure like on AWS where i can provision a NAT gateway or NAT instance on public subnet and let the private instances have internet connection
I also tried using NAT Gateway on Azure but it doesn't work unless i assign public ip to VM which is not what i want
I have two subnets lets say public_subnet & private_subnet , now i can ssh to my private vm from a jump but the thing is when i login to my private vm i cant install any package or even not able to ping or curl to any website. Both subnets were created using terraform so the configuration of subnets are all same there is no change is subnet configuration
Azure VMs have internet access by default, you dont have to do anything for them to have outbound access. It just works. Even without the public IP
There's two possibilities:
First one, under the same Vnet, you provision you VM without a public ip adress and then access it using Azure Bastion. You can find more details here.
Second one, is to provision two or more VMs in the same subnet one with public IP and the other without a public IP. and then access the one with private IP from the one with public IP.
I'm using the ACI in a private VNET. My problem is, the outgoing ip from this container is not my public IP used in Azure Gateway, is some random ip.
There's some way to fix somehow this outgoing ip from some container using ACI?
OBS: I tested with a public container, I had a public ip to incoming, but for outgoing was different :|
Thanks!
For your issue, when you create the ACI in the VNET, you just can access the resources inside the VNET and the outgoing IP is a private IP of the VNET, so the IP is static if you do not delete the ACI.
When you create a public ACI, it can access the Internet. This time, as I think, the ACI has two public IP, one is the public IP or the FQDN of the ACI to access from the Internet. And another is the public IP of the host machine that the ACI deploy in. When you access the ACI from the Internet, you need to use the public IP or the FQDN which Azure provide you. But when you access the Internet inside the ACI, the outgoing IP is the host machine's public IP. You cannot decide which host machine you can use, so does public IP of the host machine.
If you need to decide the outgoing IP and must be a static one. You can install the docker server in the VM with a static public IP, then create containers in the VM. Then the outgoing IP is the public IP of the VM.
Or you can use the AKS, create the pod and associated with a service that uses the Load Balancer type. Then the outgoing IP is also static and it's the service public IP.
I've recently setup a point to site VPN on Azure. In doing so I have created:
Azure Virtual Network
Azure Virtual Network Gateway
Azure Virtual Network Gateway IP (static)
Azure VM
I was under the impression that any VM set to use the above said Virtual Network would all share the same public IP? However it appears that the Azure VM i setup is instead using its own dynamic public IP.
Is there a way to route any VM on the Custom Virtual Network I created through one public IP? IF so - how can I do this?
According to your description, you have create a point-to-side VPN. in this scenario, we can remove the public IP addresses from VMs, then you can access your VMs with private IP addresses via VPN.
You are correct - I have the VPN working correctly. My only concern is this, it'd be great that if any of those VM's in that private network shared the same static IP - that way I could grant access to that IP in my firewall to other systems i have in other hosting platforms (as they are all typically locked down by ip).
It sounds like your reference to availablity sets may be the phrase i was looking for to further google.. i will check it out and let me know
please let me know if anything I added above changes your answer/recommendations :)

You are talking about Azure ASM module (classic). In ASM module, VMs can use the same public IP address(NAT).
However it appears that the Azure VM i setup is instead using its own
dynamic public IP.
In Azure resource module, we can create Azure VMs with different Public IP addresses.

According to your description, you have create a point-to-side VPN. in this scenario, we can remove the public IP addresses from VMs, then you can access your VMs with private IP addresses via VPN.
If you want to access those VMs from Internet and use one public IP address, we can create VMs in the same availability set, and deploy a Internet facing load balancer, then add NAT rules to them, in this way, we can access those VMs use the same public IP address and different ports.
