sleep	1

nl
nl
say	By default, for 
em	rootless
say	 mode, Podman will pick
nl
em	slirp4netns
say	 to operate the network.
nl
nl
say	Let's start a container with it
sleep	1

ns1	cd __STATEDIR__/podman
ns1b	./bin/podman run --rm -ti alpine sh
sleep	2

nl
say	and one with 
em	pasta

ns2	cd __STATEDIR__/podman
ns2b	./bin/podman run --net=pasta --rm -ti alpine sh
sleep	2

nl
nl
say	We can observe some practical differences:
nl

ns1b	ip addr show
sleep	3
say	- slirp4netns uses a predefined IPv4 address
hl	NS1
sleep	2

ns2b	ip addr show
sleep	3
say	,
nl
say	  pasta copies addresses from the host
hl	NS2
sleep	2

nl
say	- slirp4netns uses 
em	tap0
say	 as interface name
hl	NS1
sleep	2

say	, pasta
nl
say	  takes an interface name from the host
hl	NS2
sleep	2

nl
say	- same for routes:

ns1b	ip route show
sleep	3
say	 slirp4netns defines its own
nl
say	  gateway address
hl	NS1
sleep	2

say	, pasta copies it from the host
ns2b	ip route show
ns2b	ip -6 route show
sleep	5

nl
nl
say	Let's check connectivity...
sleep	2
ns1b	wget risotto.milane.se
ns2b	wget myfinge.rs
sleep	2
say	 fine.
sleep	5
nl
nl

say	Let's run a service in the container,
nl
say	configuring port forwarding first
sleep	5

ns1b	exit
sleep	2
ns1b	podman run --rm -p 8080:8080/tcp -ti alpine sh
sleep	5

ns2b	exit
sleep	2
ns2b	./bin/podman run --net=pasta --rm -p 8081:8081/tcp -ti alpine sh
sleep	5

nl
nl
say	...and now actually start the service
ns1b	apk add thttpd
ns2b	apk add thttpd
ns1b	>index.html cat << EOF
ns1b	<!doctype html><body>Hello via slirp4netns</body>
ns1b	EOF
ns2b	>index.html cat << EOF
ns2b	<!doctype html><body>Hello via pasta</body>
ns2b	EOF
ns1b	thttpd -p 8080
ns2b	thttpd -p 8081

sleep	3

nl
say	that it's accessible.

nl
nl
say	What about performance, you might ask.
nl
say	For simplicity, we'll measure between init
nl
say	namespace (the "host") and container. To do
nl
say	that, we need to allow the container direct
nl
say	access to the host, which needs an extra option
nl
say	in slirp4netns. Let's restart that container,
nl
say	while also mapping ports for iperf3 and neper.
nl
sleep	3

ns1	exit

ns1b	podman run --rm --net=slirp4netns:allow_host_loopback=true,enable_ipv6=true -p 5221-5222:5221-5222/tcp -p 5221-5222:5221-5222/udp -ti alpine sh
sleep	5
nl
nl
say	pasta allows that by default, so we wouldn't need
nl
say	to touch the container using pasta, but let's
nl
say	take the chance to look at passing extra options
nl
say	there as well.
nl
nl
ns2	exit

say	Options after '--net=pasta:' are the same as
nl
say	documented for the command line of pasta(1).
nl
say	For example, we can enable packet captures
sleep	3
ns2b	./bin/podman run --net=pasta:--pcap,demo.pcap --rm -ti alpine sh
sleep	5

say	,
nl
say	and generate some traffic we can look at.
nl
sleep	2
ns2b	wget -O - lameexcu.se
sleep	2
hostb	tshark -r demo.pcap tcp
sleep	5

nl
say	But back to performance now. By the way,
nl
say	pasta can also forward ports through the
nl
say	loopback interface for improved throughput.
nl
say	Let's configure that.
nl
sleep	2
ns2b	exit
sleep	1
ns2b	./bin/podman run --net=pasta:-T,5213-5214,-U,5213-5214 -p 5223-5224:5223-5224/tcp -p 5223-5224:5223-5224/udp --rm -ti alpine sh
sleep	5

nl
say	In slirp4netns mode, Podman enables by
nl
say	default the port forwarder from 'rootlesskit'
nl
say	for better performance.
nl
say	However, it can't be used for non-local
nl
say	mappings (traffic without loopback source 
nl
em	and
say	 destination) because it doesn't preserve
nl
say	the correct source address as it forwards
nl
say	packets to the container.
sleep	3
nl
nl
say	We'll check non-loopback mappings first for
nl
say	both pasta and slirp4netns, then restart the
nl
say	slirp4netns container with rootlesskit and
nl
say	switch to loopback mappings. pasta doesn't
nl
say	have this limitation.
nl
nl
say	One last note: slirp4netns doesn't support
nl
say	forwarding of IPv6 ports (to the container):
nl
say	github.com/rootless-containers/slirp4netns/issues/253
nl
say	so we'll skip IPv6 tests for slirp4netns as
nl
say	port forwarder (on the path to the container).

sleep	5

nl
