Helpful Docker CLI commands (1.13.x+ syntax)

Some helpful commands for Docker CLI

With release 1.13, Docker has greatly simplified interacting with the various assets docker containers use to run. These components include containers, networks, volumes, and images.

  • List all images: docker image ls -a

  • List all containers: docker container ls -a

  • Stop all containers: docker container stop $(docker container ls -aq)

  • Remove all stopped containers: docker container rm -v $(docker container ls -aq)

  • Pull new images: docker pull : (default version is :latest)

ElasticSearch installation, EC2 instance provisioning, logstash configuration etc.

Provisioning EC2 instance for ElasticSearch

EC2 instance type

Use c3.xlarge instance or c3.2xlarge instance to store ElasticSearch server. We need a fair bit of RAM and computing power, as well as 2 SSD disks for storage. We need to choose exising IAM role or create a new one so that ElasticSearch can seamlessly discover other cluster nodes hosted on EC2. Also, don't forget to add both SSDs to the list of devices (/dev/sdb and /dev/sdc).

Linux system modification

Using JetBrains tools with SQL Server LocalDB

How to set up a connection to LocalDb using JetBrains IDEs

Microsoft does not provide suport for LocalDb using the Microsoft driver. Use jTds.

  • Add a Sql Server (jTds) or LocalDb driver
  • Select LocalDb next to URL type
  • Find LocalDb executable at C:\Program Files\Microsoft Sql Server\<version>\Tools\Binn\SqlLocalDB.exe
  • Enter the name of the database
  • Select the instance your db runs on
  • Use windows domain auth (You don't need to set it up this way, but it is the easiest to do so)

  • To view your current branch and changes: git status
  • To view commit history on current branch: git log
  • To get lastest code: git pull origin <branch_name> while in your repostory directory
  • To view all local branches: git branch
  • To create a branch: git checkout -b <branch_name> while in your repostory directory
