SFTP Container

This container enables you to run SFTP on Openshift and is fully compatible with Lagoon

There are a few caveats:

• The SFTP Container will run on a high port which you can't influence
• Passwordless Authentication is not yet implemented

Installation on an lagoon project

docker-compose.yml

First we need to add the container to the docker-compose.yml

services:
  sftp:
    build:
      context: .
      dockerfile: Dockerfile.sftp
    labels:
      lagoon.type: sftp-persistent
      lagoon.template: lagoon/sftp-persistent.yml
      lagoon.persistent.name: nginx # mount the persistent storage of nginx into this container
      lagoon.persistent: /home/sftpupload/upload/ # location where the persistent storage should be mounted
    environment:
      # change following keys based on your generated keys
      SSH_HOST_ED25519_KEY: '-----BEGIN OPENSSH PRIVATE KEY-----CHANGEME'
      SSH_HOST_RSA_KEY: '-----BEGIN RSA PRIVATE KEY-----CHANGEME'
    ports:
      - 2222
    user: '111111111'

Also add following parts to your code:

• Folder sftp-container
• Dockerfile.sftp
• Openshift Template sftp-persistent.yml
• .lagoon.env.{ENVIRONMENT}

Generate Keys

Generate the keys needed with helpers/generatekeys.sh

Add those keys to your docker-compose.yml

environment:
    # change following keys based on your generated keys
    SSH_HOST_ED25519_KEY: '-----BEGIN OPENSSH PRIVATE KEY-----CHANGEME'
    SSH_HOST_RSA_KEY: '-----BEGIN RSA PRIVATE KEY-----CHANGEME'

And to your .lagoon.env.ENVIRONMENTNAME:

SSH_HOST_ED25519_KEY="-----BEGIN OPENSSH PRIVATE KEY-----CHANGEME"
SSH_HOST_RSA_KEY="-----BEGIN RSA PRIVATE KEY-----CHANGEME"

Change username and password

Change the Environment variables SFTP_USER and SFTP_PASSWORD in the Dockerfile.sftp

ENV SFTP_USER 'sftpupload'
ENV SFTP_PASSWORD 'thispasswordneedstobechanged'

Build container

After that you should be able to run docker-compose build sftp and sucessfully build the SFTP contianer.

Open Openshift Nodeport

In order to access the container from outside we need to open a port. Best ask your lagoon administrator to get this done for you.

apiVersion: v1
kind: Service
metadata:
  name: sftp
spec:
  ports:
    - name: 2222-tcp
      nodePort: XXXXXX
      port: 2222
      protocol: TCP
      targetPort: 2222
  selector:
    service: sftp
  sessionAffinity: None
  type: NodePort
status:
  loadBalancer: {}

Insipration: This work is inspired by the SFTP container of atmoz/sftp. Thanks!
