How to install strongswan in docker container

1. Start a ubuntu container. I started it with docker compose. The configuration file of compose is

services:
  ipsec-strongswan:
    image: ubuntu:22.04
    container_name: ipsec-strongswan
    cap_add:
      - NET_ADMIN
      - SYS_ADMIN
      - SYS_MODULE
    command: "tail -f /dev/null" # Example: Keep the container running, but won't do anything actual    volumes:
      - /opt/services/ipsec-strongswan/:/etc/
      - /opt/services/ipsec-strongswan/:/etc/
      - /opt/services/ipsec-strongswan/USERTrust_RSA_Certification_Authority.pem:/etc//cacerts/USERTrust_RSA_Certification_Authority.pem
      - /opt/services/ipsec-strongswan/:/etc//
      - /opt/services/ipsec-strongswan/log:/var/log/strongswan
    #Port is for 3proxy    ports:
      - 1180:1080
networks:
  default:
    name: sill

sudo docker compose -f  up -d

2. Enter the container

sudo docker exec -it ipsec-strongswan /bin/bash

3. Start the installation

apt-get update
apt-get install strongswan libcharon-extra-plugins

Install some common software

apt-get install vim iputils-ping curl mtr

My configuration is already loaded in the compose file, so it doesn't work. Start directly

# Start ipsecipsec restart
# Connection uk2ipsec up uk2

If the connection is successful, the connection ‘uk2’ was established successfully
View status

ipsec statusall

Stop the connection

ipsec down uk2

Stop ipsec

ipsec stop
