Instead of starting python server:

nano Dockerfile

# Use a basic image like Ubuntu or Alpine
FROM ubuntu:20.04

# Install required packages
RUN apt-get update && apt-get install -y \
    python3 \
    python3-pip \
    vim \
    curl \
    && rm -rf /var/lib/apt/lists/*

# Copy missile server files (if any)
# COPY /local/path/to/files /path/in/container

# Expose any necessary ports
EXPOSE 8000

# Set a default command
CMD ["sleep", "infinity"]

docker build -t missile_server_image .

docker run -d --name missile_server -p 8000:80 missile_server_image

Find IP address

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' missile_server

nano inventory.ini

[missile_server]
missile_server ansible_host=<container_ip> ansible_user=root ansible_connection=docker

touch backup_server.yml

---
- hosts: missile_server
  become: yes
  tasks:
    - name: Create launch missile script
      copy:
        content: |
          #!/bin/bash
          sleep 1
          echo "Launching missile..."
          # Missile launch logic
        dest: /tmp/launch_missile
        mode: '0755'

ansible-playbook -i inventory.ini backup_server.yml

Kinda works: default.conf file

server {
    listen 80;
    server_name localhost;

    location / {
        root /usr/share/nginx/html;
        index index.html;
    }
}

docker run -d --name missile_server -p 80:80 -v $(pwd)/html:/usr/share/nginx/html nginx:alpine

- hosts: missile_server
  become: yes
  tasks:
    - name: Create directory for HTML files
      file:
        path: /usr/share/nginx/html
        state: directory
        mode: '0755'

    - name: Copy test file to NGINX server
      copy:
        content: |
          This is a test file.
        dest: /usr/share/nginx/html/test.txt
        mode: '0644'

We can use Ad-hoc commands to run scripts:

ansible missile_server -i inventory.ini -m command -a "/usr/share/nginx/html/abort_missile.sh" --become

ACCESS NGINX

docker run -d -p 80:80 --name command_server nginx:alpine

[missile_server] command_server ansible_connection=docker

docker run -d --name command_server -p 80:80 nginx:alpine /bin/sh -c "apk add --no-cache python3 && tail -f /dev/null"

docker run -d --name command_server -p 80:80 nginx:alpine /bin/sh -c "apk add --no-cache python3 py3-pip && pip3 install --upgrade pip && pip3 install ansible && tail -f /dev/null"

docker run -d --name command_server -p 80:80 -u 1000:1000 nginx:alpine /bin/sh -c "apk add --no-cache python3 py3-pip && pip3 install ansible && tail -f /dev/null"

#!/bin/bash echo "Hello from Ansible!"
