list of useful containers

Here is a list of some of the containers those I use frequently. Here is how to install docker
First make sure that you are a root user. And there is enough disk space available.

# install docker on AWS linux

yum install -y docker

# You can install docker on centOS version 7 if you have 64-bit version

cat /etc/redhat-release

sudo yum remove docker docker-common container-selinux docker-selinux docker-engine

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo

yum makecache fast

yum install docker-ce

service docker start

# start docker
vi /etc/sysconfig/docker-storage

DOCKER_STORAGE_OPTIONS="--storage-opt dm.basesize=200G"

/etc/init.d/docker start

# Install docker-compose
curl -L`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

# Install aliases
curl -sf -L | sh

Editing storage options above will allow bigger containers (upto 200 GB) to be loaded. The container may get out of space once you start saving data into it.


In order to use node application within docker environment, you can use the official node image that can be found here...

Change to the directory where you have already written code and add the dockerfile with these 2 lines...

$ vi Dockerfile
FROM node:4-onbuild

Once your script is ready, you need to build an image...

$ docker build -t shantanuo/my-nodejs-app .

And run the node application...

$ docker run -p 8888:8888 -d shantanuo/my-nodejs-app

You can push this image to docker hub as a private or public repository.

docker login

docker push shantanuo/my-nodejs-app


ofifical mysql repository

mkdir -p /storage/test-mysql/datadir
docker run -d -p 3306:3306  -e MYSQL_ALLOW_EMPTY_PASSWORD=yes  -v /my/custom:/etc/mysql/conf.d  -v /storage/test-mysql/datadir:/var/lib/mysql   -v /my/custom:/etc/mysql/conf.d  mysql:5.6

(size: 100MB)
Just by changing the name to test-mysql2 we can set up another mysql container. Instead of mysql official version, we can use tutum/mysql which has customized installation.

fixed the bug in the official mysql image

Percona with tokuDB

docker run -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -e INIT_TOKUDB=1 -d percona/percona-server

log in to the container and run this command to enable tokudb if "show engines" command does not show tokudb.

ps_tokudb_admin --enable

# backup of mysql hosted in the folder /storage of another container named mysql-server

docker run -it \
--link mysql-server:mysql \
-v /storage/mysql-server/datadir:/var/lib/mysql \
-v /storage/backups:/backups \
--rm=true \
severalnines/mysql-pxb \
sh -c 'exec /'

# backup of mysql from hosted machine

docker run -it \
-v /var/lib/mysql:/var/lib/mysql \
-v /storage/backups:/backups \
--rm=true \
severalnines/mysql-pxb \
sh -c 'exec innobackupex --host="$hostname" --port="3306" --user=root --password="$rootpassword" /backups'


# cluster control container:
docker run -d --name clustercontrol -p 5000:80 severalnines/clustercontrol


1) official container

# command to install both, elasticsearch and kibana
docker run -d -p 9200:9200 -p 5601:5601 nshou/elasticsearch-kibana

Or use the following with volume attached:

docker run -d -p 5601:5601 -p 5000:5000  -p 9200:9200 --ulimit nofile=65536:65536 -v /mydata:/var/lib/elasticsearch kenwdelong/elk-docker:latest

Here are 2 commands to start Elasticsearch with Kibana using docker official version.

# cat /tmp/elasticsearch.yml
script.inline: on
script.indexed: on

# docker run -d -v /tmp/:/usr/share/elasticsearch/config  -p 9200:9200 -p 9300:9300  -e ES_HEAP_SIZE=1g elasticsearch:2

Find the name of the container and link it to kibana by changing kibana_name_here below like this...

# docker run -d -p 5601:5601 --link   kibana_name_here:elasticsearch -e ELASTICSEARCH_URL=http://elasticsearch:9200 kibana

Login to the newly created elastic container and install plug-ins
docker exec -it container_id bash

# pwd

# bin/plugin install analysis-phonetic

Once the plugin is installed, restart the container so that elastic service will be restarted....
# docker restart c44004a47f46

2) custom container

elastic - customize elasticsearch installation and maintenance

3) elastic with kibana version 5
docker run --name myelastic -v /tmp/:/usr/share/elasticsearch/config  -p 9200:9200 -p 9300:9300 -d elasticsearch:5.0

docker run -d -p 5601:5601 --link myelastic:elasticsearch -e ELASTICSEARCH_URL=http://elasticsearch:9200 kibana:5.0

# docker run -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -d elasticsearch:5

You may get this error in your logs:

Exception in thread "main" java.lang.RuntimeException: bootstrap checks failed max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

You'll need to fix up your docker host to support more vm.max_map_count. For reference:

sysctl -w vm.max_map_count=262144


adminer is the web interface to connect to any database like postgresql, mysql or oracle
Instead of linking adminer on any port, use --net=host to use the default port 80 of host machine. It will also use default mysql port 3306 that is fortunately linked to mysql container as shown above.

If you do not want to add one more parameter i.e. --net then use the default "bridge" network protocol. You will need to use the following command to find the IP address of the docker host.

# ip addr show docker0

This command will show the docker host IP address on the docker0 network interface.

redshift connection:

docker run -i -t --rm -p 80:80 --name adminer shantanuo/adminer

The above command will log-in to docker container. You need to start apache service within container...

sudo service apache2 start

Or use any of the method mentioned below:


wget -O /tmp/index.php

connect to any database like mysql, pgsql, redshift, oracle or mongoDB

postgresql (redshift) or mysql

docker run -it -p 8060:80 -v /tmp/:/var/www/html/ shantanuo/phpadminer


docker run -d -p 8070:80 -v /tmp:/var/www/html ishiidaichi/apache-php-mongo-phalcon


docker run -d -p 8080:80 -v /tmp/:/app lukaszkinder/apache-php-oci8-pdo_oci

# not sure about how to support mssql


compact packages

1) pyrun
python versions 2 and 3 compact, without any external libraries, for basic testing like this...
here is an easy way to convince people to upgrade to python 3.0+

# docker run -it --rm shantanuo/pyrun:2.7 python
>>> 3/2

# docker run -it --rm shantanuo/pyrun:3.4 python
>>> 3/2

Python 2.7 version returns absolute value 1 while 3.4 version correctly returns 1.5

2) staticpython 
4 MB single file python package!

3) socket 
 python with application files

Complete python package

4) conda official 
Official python installation:

And here is the command to start miniconda and ipython together...

docker run -i -t -p 8888:8888 -v /tmp:/tmp continuumio/miniconda3 /bin/bash -c "/opt/conda/bin/conda install jupyter -y --quiet && cd /tmp/ && /opt/conda/bin/jupyter notebook --notebook-dir=/tmp --ip='*' --port=8888 --no-browser --allow-root"

5) miniconda customized
Here is an impage with pandas and sqldf modules

# Start ipython container that is based on miniconda image in a screen session
docker run -p 7778:7778 -t shantanuo/miniconda_ipython_sqldf /bin/bash

# better start with environment variables
docker run -p 7778:7778 \
-t shantanuo/miniconda_ipython_sqldf /bin/bash

# Log-in to newly created container
docker exec -it $(docker ps -l -q) /bin/bash

# Start ipython notebook on port 7778 that can be accessed from anywhere (*)
cd /home/
ipython notebook --ip=* --port=7778

# and use the environment keys in your code like this...
import boto3
import os
s3 = boto3.client('s3',aws_access_key_id=os.environ['DEV_ACCESS_KEY'], aws_secret_access_key=os.environ['DEV_SECRET_KEY'])

application containers

Here is an example from amazon about how to build your own container with php application.

Utility containers

1) myscan 

Use OCR to read any image.
alias pancard='docker run -i --rm -v "$(pwd)":/home/ shantanuo/myscan python / "$@"'


pancard 1crop.jpg

2) panamapapers 

container with sqlite database ready for query

3) newrelic
newrelic docker image that works like nagios

docker run -d -v /dev/shm:/dev/shm -p 4444:4444 selenium/standalone-chrome

The Hub url...

6) Deploying registry server
#Start your registry:
docker run -d -p 5000:5000 --restart=always --name registry registry:2

#You can now use it with docker. Tag any image to point to your registry:
docker tag image_name localhost:5000/image_name

#then push it to your registry:
docker push localhost:5000/image_name

# pull it back from your registry:
docker pull localhost:5000/image_name

# push the registry container to hub
docker stop registry
docker commit registry
docker push registry

7) Docker User Interface
docker run -d -p 9000:9000 -v /var/run/docker.sock:/docker.sock --name dockerui abh1nav/dockerui:latest -e="/docker.sock"

Better user interface with shell access:

docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer

8) docker clean up container
docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm martin/docker-cleanup-volumes --dry-run

9) prometheus monitoring
check port 9090 and cadvisor on 8080

git clone
cd prometheus/

/usr/local/bin/docker-compose  up -d

10) open refine utility
# docker run --privileged -v /openrefine_projects/:/mnt/refine -p 35181:3333 -d psychemedia/ou-tm351-openrefine

with tokumx compression engine
docker run -p 27017:27017 -v /tokudata:/data/db -d ankurcha/tokumx

# create alias for bsondump command

# alias bsondump='docker run -i --rm -v /tmp/:/tmp/ -w /tmp/ mongo bsondump "$@"'

# bsondump data_hits_20160423.bson > test.json

# alias mongorestore='docker run -i --rm -v /tmp/:/tmp/ -w /tmp/ mongo mongorestore "$@"'

# mongorestore --host `hostname -i` incoming_reports_testing.bson

docker run -p 8083:80 --link gigantic_pike:mysql -e WORDPRESS_DB_NAME=wpdb -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=india -d wordpress

And we can also use docker compose the start and link db and application containers.

vi docker-compose.yml

version: '2'

     image: mysql:5.7
       - "./.data/db:/var/lib/mysql"
     restart: always
       MYSQL_ROOT_PASSWORD: wordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

       - db
     image: wordpress:latest
       - db
       - "8000:80"

# login to your container:
docker exec -it container_id bash

# change to opt directory
cd /opt/
mkdir public

# a test file
curl > public/index.html

# start passenger:
passenger start

20) update containers
# monitor the containers named "nginx" and "redis" for updates

docker run -d \
  --name watchtower \
  -v /var/run/docker.sock:/var/run/docker.sock \
  centurylink/watchtower nginx redis

21) sematext monitoring
