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

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
