systemctl command doesn't work inside of amazonlinux:latest container

Question

When running "docker run --rm amazonlinux systemctl --version" to pull the latest amazon linux 2 docker container and checking the version of systemctl, I get this output:  
  
docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"systemctl\": executable file not found in $PATH": unknown.  
  
However I would expect a similar output for pulling the latest centos container like when running "docker run --rm centos systemctl --version" which gives me the output:  
  
systemd 239  
_PAM _AUDIT _SELINUX _IMA -APPARMOR _SMACK _SYSVINIT _UTMP _LIBCRYPTSETUP _GCRYPT _GNUTLS _ACL _XZ _LZ4 _SECCOMP _BLKID _ELFUTILS _KMOD _IDN2 -IDN +PCRE2 default-hierarchy=legacy  
  
The systemctl command even works when trying it on an amazon linux 2 AMI, so I'm not sure why this doesn't work for the docker container. Also, I know that I am pulling an amazon linux 2 docker image from the command above because when I run "docker run --rm amazonlinux cat /etc/os-release" to print out the OS details I see:  
  
NAME="Amazon Linux"  
VERSION="2"  
ID="amzn"  
ID_LIKE="centos rhel fedora"  
VERSION_ID="2"  
PRETTY_NAME="Amazon Linux 2"  
ANSI_COLOR="0;33"  
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"  
HOME_URL="https://amazonlinux.com/"

Answer

By default, systemd is not installed in the Amazon Linux 2 container image.  
  
Try this:

```
 yum install -y /usr/bin/systemctl; systemctl --version
```

Answer

This is a non-fully tested solution, but solves me the problem on `amazonlinux:1` who it is under EOL extended window time (consider this solution as your own risk):

```
cat /etc/os-release | grep CPE_NAME
CPE_NAME="cpe:/o:amazon:linux:2018.03:ga"

curl -o /usr/local/bin/systemctl https://raw.githubusercontent.com/gdraheim/docker-systemctl-replacement/master/files/docker/systemctl.py\
    && chmod +x /usr/local/bin/systemctl

systemctl --version

systemd 219
  - via systemctl.py 1.5.7113
-PAM -AUDIT -SELINUX -IMA -APPARMOR -SMACK +SYSVINIT -UTMP -LIBCRYPTSETUP -GCRYPT -GNUTLS -ACL -XZ -LZ4 -SECCOMP -BLKID -ELFUTILS -KMOD -IDN
```
