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
yum install -y docker

# 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 https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

# Install aliases
curl -sf -L https://raw.githubusercontent.com/shantanuo/docker/master/alias.sh | 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.

Node.js

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

https://hub.docker.com/r/library/node/

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

$ vi Dockerfile
FROM node:4-onbuild
EXPOSE 8888

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
username:shantanuo
password:XXXX

docker push shantanuo/my-nodejs-app

MySQL

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

https://github.com/shantanuo/mysql

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
# 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 /run_backup.sh'

# 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'

Utilities

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

elastic

1) official container

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

# cat /tmp/elasticsearch.yml
script.inline: on
script.indexed: on
network.host: 0.0.0.0

# docker run -d -v /tmp/:/usr/share/elasticsearch/config  -p 9200:9200 -p 9300:9300  -e ES_HEAP_SIZE=30g elasticsearch

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
/usr/share/elasticsearch

# 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

https://www.elastic.co/guide/en/elasticsearch/guide/current/_file_descriptors_and_mmap.html

adminer

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:

download

wget http://www.adminer.org/latest.php -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

mongoDB

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

oracle

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

# not sure about how to support mssql

python

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
1

# docker run -it --rm shantanuo/pyrun:3.4 python
>>> 3/2
1.5

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:

https://github.com/ContinuumIO/docker-images

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 \
-e DEV_ACCESS_KEY=XXX -e DEV_SECRET_KEY=YYY \
-e PROD_READONLY_ACCESS_KEY=XXX -e PROD_READONLY_SECRET_KEY=YYY \
-e PROD_READWRITE_ACCESS_KEY=XXX -e PROD_READWRITE_SECRET_KEY=YYY \
-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.

https://github.com/awslabs/ecs-demo-php-simple-app
