Local Docker Setup for SFTP Server

Prerequisites

Docker installation is completed in the system. In the below example, colima is used on Mac System.

Step 1: Start the colima with colima start

Step 2: Configure docker in Intellij

Install the Docker plugin in Intellij - https://plugins.jetbrains.com/plugin/7724-docker

Configure the Docker plugin

To find the TCP socket - Engine API URL for colima, run docker context ls command. Sample value is given below.

unix:///Users/pranayp/.colima/aarch64/docker.sock

Configure the Docker executable and Compose executable

To find Docker executable and Docker Compose executable, run the below command

Step 3: Prepare the docker-compose file

Save the below content in docker-compose file

docker-compose.yml

version: "3.9"
# https://docs.docker.com/compose/compose-file/

services:
  sftp-server:
    container_name: sftp-server
    image: antrea/sftp #https://hub.docker.com/r/antrea/sftp
    platform: linux/amd64 #Change the platform as needed
    ports:
      - "9922:22"
    volumes:
      - ./sftp_test_data:/home/sftpuser/upload/sftp_test_data  # Mount a local directory to the container
    environment:
      SFTP_USERS: "sftpuser:pass:1001:100"  # Set the username, password, UID (user id), and GID (group user id)
      SFTP_CHROOT: "/home/sftpuser"  # Restrict user to the home directory

networks:
  default:
    name: default_network

Since, we are attaching a volume of local sftp_test_data folder, create a folder and add some test files there.

Step 4: Run the docker-compose file

Step 5: Connect the sftp server via any tools

Here, we will use FileZilla Client. Download and Install the FileZilla client from below url

https://filezilla-project.org/download.php?type=client#close

Open the FileZilla Client

Add below details as we configure in docker-compose file

Host: sftp://127.0.0.1
Username: sftpuser
Password: pass
Port: 9922
