Experiment LWC

Just learning how container works

Prerequesites

install cgdelete

update iptables FORWARD policy

iptables --policy FORWARD ACCEPT

Quickstarts

Quickstarts with alpine as base image

mkdir -p rootfs/alpine-minirootfs-3.15.0-x86_64
tar -xf ./rootfs_store/alpine-minirootfs-3.15.0-x86_64.tar.gz -C ./rootfs/alpine-minirootfs-3.15.0-x86_64

then, start 2 containers

[Container1]

sudo ./experiment_lwc --opt run --config samrunple_config.yaml

[Container2]

sudo ./experiment_lwc --opt run --config sample_config_2.yaml

those 2 containers can communicate with each others, like this

[Container2]

/ # ping 10.10.10.2
PING 10.10.10.2 (10.10.10.2): 56 data bytes
64 bytes from 10.10.10.2: seq=0 ttl=64 time=0.091 ms
64 bytes from 10.10.10.2: seq=1 ttl=64 time=0.043 ms

Build

go build -trimpath

Usage

./experiment_lwc --help
./experiment_lwc --opt run --help
./experiment_lwc --opt inspect --help
./experiment_lwc --opt cleanup --help
./experiment_lwc --opt network --help

Cleanup

Run cleanup.sh to clean the database and container directory

TODOs

• Container can connect to internet
• Add seccomp filter to container process
