Hi, As you know, kubernetes decide to remove docker shim starting from 1.25. We were using docker in docker image in jenkins to run docker commands in previous kubernetes versions. But after 1.25, it is not possible I used pod below to run testcontainers tests with maven and define environment variables 

kubectl apply -f - <<EOF
apiVersion: v1
kind: Pod
metadata:
 name: podman-priv
spec:
 containers:
   - name: priv
     image: quay.io/podman/stable
     args:
       - sleep
       - "1000000"
     securityContext:
       privileged: true
EOF
DOCKER_HOST="unix:///run/user/$UID/podman/podman.sock" \
TESTCONTAINERS_RYUK_DISABLED="true"

it gave the error /var/run/docker.sock: no such file or directory. Do you think podman can replace docker in terms of testcontainers usage in kubernetes 1.25+?

I don't have an experience of running Podman in Kubernetes. But the error message states that Testcontainers searches docker.sock at /var/run/docker.sock instead of /run/user/$UID/podman/podman.sock. Make sure environment variables DOCKER_HOST and TESTCONTAINERS_RYUK_DISABLED are set.
