Recommended Docker Images

whoami

This is a great simple container for troubleshooting network connectivity. Once started it will give you a webserver that will reply with header info or using get vars for things like /data?size=1&unit=MB or ?wait=5s

docker run -d --name=whoami -p 80:80 containous/whoami

version: "3.8"
services:
  whoami:
    image: containous/whoami:latest
    ports:
      - "80:80"

iperf3

networkstatic/iperf3
iperf3 is a great container to leave running to do point to point bandwidth tests on a network

docker run -d --name=iperf3-server -p 5201:5201 networkstatic/iperf3 -s

Then from any other machine in the LAN you can max speed test to this one with:

iperf3 -c hostname.example.com

And you will get results that look like:

[ 4] 0.00-10.00 sec 2.80 GBytes 2.40 Gbits/sec sender

OpenSpeedTest

https://openspeedtest.com/

Don’t want to have to install iperf3 on both the server and client-side to get speed results? OpenSpeedTest is an in-browser client that can get you download/upload speeds.

docker run --restart=unless-stopped --name=openspeedtest -d -p 7777:3000 openspeedtest/latest

This is a LAN server with 10G ethernet, showing a bottleneck at 4.5G

Portainer

Portainer is a great web interface that lets you control docker

docker volume create portainer_data #otherwise you get some random named volume
docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

Then access it with http://localhost:9000

SMTP Relay to Amazon SES

Many services have trouble talking to well-secured SMTP servers like Amazon SES. A relay is a nice way to allow those devices or services to talk to a simpler server that will then forward it to SES.

docker run -d -p 25:25 --name smtp-to-ses-relay --restart=always -e SMTP_USERNAME=abcdefgh -e SMTP_PASSWORD=123abc -e AWS_REGION=us-west-2 building5/ses-relay:latest

version: "3.8"
services:
  ses-relay:
    image: building5/ses-relay:latest
    environment:
      SMTP_USERNAME: ABCD1EFGHI2JK3LMNOPQ
      SMTP_PASSWORD: abcDefgHi1jK2aAAAAaAAAa3AaaAAAABCDefg3hij4K
      AWS_REGION: us-west-2
    ports:
      - "25:25"

Splunk

https://github.com/splunk/docker-splunk

This is a great log analyzer that lets you load in any text logs and search for patterns or create dashboards.

By default, when you create a Splunk Docker container, it will enable a Splunk Trial license which is good for 30 days from the start of your instance.

500MB/day log ingest
Allowed 3 license violations in last 30 days (you can ingest any amount of data in 24h)
30 Day Trial, can register to get to Splunk Free license
- no alerting/monitoring
- no users
- no report clustering

docker run -d -p 8000:8000 -e "SPLUNK_START_ARGS=--accept-license" -e "SPLUNK_PASSWORD=<password>" --name splunk splunk/splunk:latest

Uses ~3GB of memory and a constant 5% cpu idling. It also will spike its CPU when the container is left alone for a long time.

Privatebin

https://hub.docker.com/r/privatebin/nginx-fpm-alpine

PrivateBin is a minimalist, open-source online pastebin where the server has zero knowledge of pasted data. Data is encrypted and decrypted in the browser using 256bit AES in Galois Counter mode.

version: '3'
services:
  app:
    image: 'privatebin/nginx-fpm-alpine:latest'
    read_only: true #for security
    ports:
      - '8080:8080'
    volumes:
      - /mnt/content-ebs/privatebin/data:/srv/data
      - /mnt/content-ebs/privatebin/conf.php:/srv/cfg/conf.php

Copy a config from https://raw.githubusercontent.com/PrivateBin/PrivateBin/master/cfg/conf.sample.php as conf.php

(idles at 20mb memory usage with 0% cpu)

PHP

Is a pain. The default docker images are too bare bones with the expectation you will build your own. Apache+PHP is much easier to build but nginx+PHP-FPM is still doable. I like to avoid all HTTPS/SSL in this container and instead use something like docker-router to handle certificate generation. I recommend using a major version tag instead of :latest as going from PHP 7 to 8 can be a bump as I expect PHP 9 will be.

<project-folder>/Dockerfile

FROM php:8-apache

RUN docker-php-ext-install mysqli
RUN apt-get update && apt-get install -y zlib1g-dev libpng-dev libzip-dev libwebp-dev libjpeg-dev libfreetype6-dev exiftool
RUN docker-php-ext-configure gd --with-freetype --with-webp --with-jpeg && docker-php-ext-install gd
RUN docker-php-ext-install exif
RUN a2enmod rewrite

Optionally, I like making a build.sh to get a nice image name and normalize versioning and updating the latest tags.

TODAY=`date -u +"%Y%m%d"`
IMAGE_NAME=PROJECT-webserver
MAJOR_VERSION=1
docker build -t ${IMAGE_NAME}:${MAJOR_VERSION}.${TODAY} .
docker tag ${IMAGE_NAME}:${MAJOR_VERSION}.${TODAY} ${IMAGE_NAME}:latest

You can try to use the stock php

docker run -d --name lan-links -v /mnt/lan-links:/var/www/html -p80:80 php:7-apache

version: '3'

services:
  web:
    image: php:7-apache
    hostname: "docker-php"
    restart: "no"
    ports:
      - 80:80
    volumes:
      - /mnt/docker-swarm-volumes-nfs/test-nginx:/var/www/html

# this pushes the container onto your actual LAN, but needs the macvlan network setup already, just leave this out if it isn't setup
networks:
  default:
    external: 
      name: on-lan-network

Jellyfin

version: '3.5'
services:
  app:
    image: jellyfin/jellyfin
    ports:
      - "8096:8096"
    volumes:
      - /Users/steve/jellyfin/config:/config
      - /Users/steve/jellyfin/cache:/cache
      - /Users/steve/jellyfin/media:/media
    environment:
      - JELLYFIN_PublishedServerUrl=http://example.com

calibre-web ebook library

docker run -d \
  --name=calibre-web \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=America/Chicago \
  -e DOCKER_MODS=linuxserver/calibre-web:calibre \

  -v /mnt/calibre-web/config:/config \
  -v /mnt/calibre-web/books:/books \
  --restart unless-stopped \
  ghcr.io/linuxserver/calibre-web

version: "3"
services:
  calibre:
    image: ghcr.io/linuxserver/calibre-web
    ports:
      - 8083:8083
    volumes:
      - /mnt/calibre-web/config:/config

      PGID: 1000
      TZ: "America/Chicago"
      DOCKER_MODS: "linuxserver/calibre-web:calibre"

On the first run, it will complain about a missing database, you have to run this to manually create the file or load in a pre-existing one.

cd /app/calibre/bin && ./calibredb restore_database --really-do-it --with-library /books

chmod 777 metadata.db

Default user is admin and password is admin123

Postgres

`docker run`

project-db:
      image: postgres
      environment:
        - POSTGRES_USER=appname
        - POSTGRES_PASSWORD=asdf1234
      volumes:
        - /mnt/appname/db:/var/lib/postgresql/data

Redis Cache

Redis is a high speed in memory key value store, its a great place to store values that don’t change often but want fast lookup time. Alot of systems render a page and just save it to redis.

version: "3"
services:
  cache:
    image: redis:7-alpine
    ports:
      - '6379:6379'
    command: redis-server --save 60 1 --loglevel warning --requirepass $PASSWORD
    volumes:
      - /mnt/redis:/data

VS Code

If you want a cloud hosted vscode that runs in your browser, this is a great way if you have a dev instance that you want fast iterations on.

version: '3'
services:
  code-server:
    image: lscr.io/linuxserver/code-server:latest
    environment:
      - TZ=America/Chicago
      - PASSWORD=asdf123
      - SUDO_PASSWORD=9abc3823Zxm
      - PROXY_DOMAIN=vscode.i.zazeski.com
      - DEFAULT_WORKSPACE=/workspace
    volumes:
      - /Users/steve/steve/serve-config/config:/config
      - /Users/steve/steve/serve:/workspace
    ports:
      - 8443:8443

VaultWarden

If you are looking for a self hosted password manager with unlimited users at no cost.

version: "3"
services:
  vaultwarden:
    image: vaultwarden/server:latest
    restart: unless-stopped
    expose:
      - 8443:443  # https
      - 8012:3012 # websocket
    env_file:
      - /mnt/vaultwarden/config.env
    volumes:
      - /etc/localtime:/etc/localtime:ro
