            It is a kind of workaround for the problem, if you can pull image using docker pull then do it on all the worker nodes and then add an


            inside the yamls where you are mentioning image name, then k8s will first check whether it is present inside the machine and if yes then directly use it

            Increase vm.max_map_count permanently in podman machine vm
            Asked 2022-Apr-01 at 04:10

            I am trying to run the Elasticsearch image on my Mac m1 laptop using podman. It will fail with the message:

            ERROR: [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch. bootstrap check failure [1] of [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

            I can solve this temporarily by using ssh to enter the podman machine vm and setting vm.max_map_count with

            sudo sysctl -w vm.max_map_count=262144

            However, if I stop and restart the podman machine vm, the setting is back to the default 65530.

            Is there a way to permanently set vm.max_map_count for the podman machine vm?

            I came across this recently too. You make have already sorted it out.

            To modify kernel parameters at boot just add an entry do one of your sysctl configs and it will be applied on reboot.

            Testcontainers with Podman in Java tests
            Asked 2022-Mar-28 at 17:00

            Is it possible to use Testcontainers with Podman in Java tests? As of March 2022 Testcontainers library doesn't detect an installed Podman as a valid Docker environment.

            Can Podman be a Docker replacement on both MacOS with Apple silicon (local development environment) and Linux x86_64 (CI/CD environment)?



            Answered 2022-Mar-28 at 17:00

            It is possible to use Podman with Testcontainers in Java projects, that use Gradle on Linux and MacOS (both x86_64 and Apple silicon).

            Prerequisites Enable the Podman service

            Testcontainers library communicates with Podman using socket file.


            Start Podman service for a regular user (rootless) and make it listen to a socket:

            Facing the same problem due to podman version upgrade.

            Seems like a version downgrade would be required to recover the containers, but haven't tried it yet.
            This issue points on deleting the machine and creating it again, but the containers would be lost

            Communicate different pods using Podman
            Asked 2022-Mar-10 at 16:08

            I am deploying several Pods using podman-compose. To do so, each pod has its own definition in a podman-compose.yaml file that I execute in rootless mode (so all containers in a Pod coexist in the same host/IP). However, I would like to make able a container in a Pod to reach a service exposed by a container in another pod.

            I know Kubernetes has the Service object that let pods communicate between them. But I don't want to use K8S...

            So my question is: Is there any 'equivalent' or workaround I could use to reach such a communication between pods? Not only in the Podman ecosystem, but in the Linux's one.

            Ideally, I would like to use a DNS that lets containers resolve the IP of other containers in other pods. Should I use my machine (where all pods are running) DNS to proxy requests between pods? And more importantly, is this a good practice?

            Sorry if the answer is pretty obvios, I am new in the IT world.

            Anyway, thank you all in advance!

            There is no analog to a Kubernetes Service object. In podman (and docker), service discovery is name-based: containers can refer to other containers by name, and there are no restrictions on what ports they can access. So if you have:

            What I am trying is to create a container isolated otherwise but having a port open for access from outside. I'd like to keep it so that container can't access internet.

            I have internal network and container that has a single port open for accessing the service.

            Solution of some sorts was to create a reverse-proxy and attach it to to the internal and to a driver:bridge network. Now the traffic to vaultwarden app goes through the other network and vaultwarden itself can't access internet.

            To allow communication between containers you need to setup a shared networks, e.g. in .yaml (this can be done as well as on ci, report in .yaml only for sake of code):

            How to add relative paths and how to mount volumes in a container with Podman
            Asked 2022-Feb-23 at 09:55

            I'd like to build a container using Podman which would contains the following:

            • a Python application
            • the Python modules I developed but which are not stored at the same place than the Python application
            • the Python environment (made with miniconda/mambaforge)
            • a mounted folder for input data
            • a mounted folder for output data

            To do that, I've added a Dockerfile in my home directory. I had to put the Dockerfile at a such high path level because it seems that it needs to be above any folder I want to add in the container. Indeed, I've tried to add folders using rising path with "../../some/path/" but it doesn't work. Then, a first question is: Is there a solution to add folders which are not below (in path) the Dockerfile?

            Below is the content of the Dockerfile:
