Hi, I would like to use Kubernetes to process batch data in a scalable and fault tolerant way (specifically to scrape data and update rows in a database). I am very new to K8s but after reading the docs I think I want to: Create a controller application which gets […]

Hey all, just curious if anyone has macvlan working in kubernetes? I’ve been using docker and macvlan for a long time. Most everything works well for me with respect to using a container with a DHCP reservation and FQDN. Lately I’ve been experimenting with different k8s configurations, and have not […]

I have setup a service on a swarm and specified the number of replicas which was straight forward but there are a few things I can’t figure out: How do I specify the number of replicas on specific nodes? Some nodes have more resources, how do I balance this? How […]

Docker desktop (Windows) question here. I’ve setup the kylemanna OpenVPN container and am trying to get the client config file off the container to use on my host. I’ve run the command to create it but can’t figure out how to move it from the container to the host. I […]

I noticed there is an option in docker-desktop that allow to change the “Docker subnet”. https://i.imgur.com/20d5VJc.png However, I’m struggling to find documentation on what it is exactly. I’ve done the usual docker network inspect, checked the WSL2 distro and my Windows host for routes but I don’t see that default […]

I am trying to figure out a couple of points … any help would be helpful. Here they are: How does one change the default directory for secrets? If I have a couple remote office locations, and they all need access to a DTR, what is the best way to […]

I am wanting to map a volume to a docker-compose file, but be able to map different paths to the root volume. I can get the volume mounted, but when I try to map a sub folder in that path it errors out. Is this possible? I know that you […]

I am looking to setup a Channels DVR container on my Mac Mini, which has an Intel iGPU. On linux I would generally map this to /dev/dri but I’m not finding the equivalent for Docker on Mac. Is hardware transcoding possible on Docker on Mac? Anyone know the correct location […]

Hi All, I am new to using Kubernetes and have built a few clusters, both k8s and with RKE. I have noticed that even if I have multiple nodes with the control plane node, I can only run kubectl commands from the node I used to create the cluster from. […]

Is anyone else having issues setting up github integration in a docker hub org? I made a service account in github (just a new user account and added to our org with full read/write, made org membership public) then linked that account to the docker hub org. Go to a […]

As you know, DDoS attacks are pretty popular nowadays. Generally, we use services like Cloudflare to protect against them as these services absorb malicious traffic. But even additional protection mechanisms (e.g., “I’m Under Attack” mode combined with a white list in Cloudflare) will not help, if you disclose your IP […]

r/docker has given great feedback multiple times about Blimp, a cloud/SaaS Docker Compose product that I’m working on to scale heavy containers to the cloud during development. So I wanted to share some updates! We now persist volumes across blimp downs, to further increase parity with Docker Compose. For more […]

I want to create a cluster from three VPSes, having one master and two worker nodes. All of them will have public IPs. I have tried such configuration with VMs using Flannel plugin and Nginx’ Ingress, but I can’t find the way to connect to the cluster service on port […]

I’ve written a blog about how we are performing out testing here at StorageOS. The part I think may be of particular widespread interest is how we are leveraging KinD in Ignite to run KinD across Ignite provisioned Firecracker VMs and how this entire setup spins up in a totally […]

Hi, I am trying to run a container with docker-compose and access it from a computer connected to the same local network as the host,when I go to , it just hangs with docker-compose It works fine by using docker directly though: docker run –name adguardhome –network host -v […]

Over the course of the first two parts of this blog series, we setup a single-node Kafka cluster on Kubernetes, secured it using TLS encryption and accessed the broker using both internal and external clients. Let’s keep iterating! In this post (part 3), we will continue the Kafka on Kubernetes […]

hello, for work I am currently running a VM with Linux Mint. I would like to ask if it is possible to replace this VM with Docker. In the VM I currently have: Connection through openfortinet to a VPN Server Firefox Browser Bash with some third party commands like lftp, […]

I am studying deploying small clusters to lots of edge sites. Think 1000 sites each with 3 lightweight nodes. They are all running pretty much the same application and should be able to keep running without a connection (so control plane is also on the edge sites) On a site […]

If I connect through “concisions/windscribe-socks-server” docker container I can use windscribe. But if I am using a simple debian or ubuntu container and I normally install the client, I can’t use windscribe, because it tells me: Error running Login when I entry the credentials. And those are the correct credentials, […]

The purpose is that I don’t want to make all the system to be under the VPN, but I want just to connect via socks to a docker container that has Windscribe in it. I am using this docker: https://hub.docker.com/r/concisions/windscribe-socks-server If I connect through socks to this container that has […]
