# Build container image
|
||
|
|
|
||
|
|
Create dockerfile for the container
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cat <<EOF | tee Dockerfile
|
||
|
|
FROM ubuntu:22.04
|
||
|
|
|
||
|
|
RUN apt update \
|
||
|
|
&& apt install -y wget systemd kmod systemd-sysv vim less iptables \
|
||
|
|
&& rm -rf /var/lib/apt/lists/*
|
||
|
|
|
||
|
|
RUN systemctl set-default multi-user.target
|
||
|
|
|
||
|
|
RUN find /etc/systemd/system /lib/systemd/system \
|
||
|
|
-path '*.wants/*' -not -name '*systemd*' -exec rm -f {} \;
|
||
|
|
|
||
|
|
CMD mkdir /workdir
|
||
|
|
WORKDIR /workdir
|
||
|
|
|
||
|
|
ENTRYPOINT ["/lib/systemd/systemd", "--system"]
|
||
|
|
EOF
|
||
|
|
```
|
||
|
|
|
||
|
|
Build container image
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker build -t ubuntu-systemd .
|
||
|
|
```
|
||
|
|
|
||
|
|
Run created container image
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run -d \
|
||
|
|
--name ubuntu-systemd-container \
|
||
|
|
--privileged \
|
||
|
|
--security-opt seccomp=unconfined \
|
||
|
|
--security-opt apparmor=unconfined \
|
||
|
|
-v /sys/fs/cgroup:/sys/fs/cgroup:rw \
|
||
|
|
--tmpfs /tmp \
|
||
|
|
--tmpfs /run \
|
||
|
|
--tmpfs /run/lock \
|
||
|
|
ubuntu-systemd
|
||
|
|
```
|
||
|
|
|
||
|
|
And now we need to run bash inside container
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker exec -it ubuntu-systemd-container bash
|
||
|
|
```
|
||
|
|
|
||
