you can use --net mynet with --network-alias myweb make sure you have podman-plugins installed then try the following here is an example podman network create mynet podman run -d --net mynet --network-alias myweb busybox httpd -f -p 80 -h /etc podman run --rm -ti --net mynet busybox wget -O - http://myweb/hosts see https://github.com/containers/podman-compose/issues/379 On Tue, Jan 4, 2022 at 4:52 PM Michael Biarnes Kiefer <mbiarnes@redhat.com> wrote:
Hi,
I am new to podman. I have this problem: The Docker option *--link* is legacy and doesn't work any-more. Using podman right now I saw that this option should be replaced somehow by *--network *or *--pod*.
The thing is I tried several things with --network or --pod but somehow two different containers running (from two different images) can't communicate to each other: Before (when Docker --link still was available): $ podman images REPOSITORY TAG IMAGE ID CREATED SIZE localhost/kiegroup/kie-server-showcase 7.63.0.Final 7de306f0d498 20 minutes ago 1.03 GB localhost/kiegroup/business-central-workbench-showcase 7.63.0.Final 446a00d242c2 10 days ago 1.11 GB
podman run -p 8083:8080 -p 8003:8001 -i -t --name business-central-wb kiegroup/business-central-workbench-showcase:7.63.0.Final (runs the 446a00d242c2 container) podman run -p 8088:8080 -i -t --name kieserver-wb --link business-central-wb:kie-wb kiegroup/kie-server-showcase:7.63.0.Final (run 7de306f0d498 container linked to 446a00d242c2)
Both Containers could communicate and share different vars.
I tried to create a network and run both containers with --network <createdNetwork> or I created a pod and run both containers with --pod <created pod> option, but somehow the running container doesn't share the needed values. I do podman inspect and look to container values - and they are there as expected.
What do I wrong? podman version 3.4.4 OS: Fedora 34
ThanX
Michael
