| CI & CD: | |
| ======== | |
| 2 core software development processes | |
| CI process of automating regular code commits followed by an automated build and test process designed to highlight intergration issues early. | |
| Additional tooling and functionality provided by Bamboo, CruiseControl, Jenkins, Go and TeamCity etc. | |
| workflow based | |
| CD takes the form of a workflow based process which accepts a tested software build payload from a CI server. Automates the deployment into a working QA, Pre-prod or Prod environment. | |
| AWS CodeDeploy and CodePipeline provide CI/CD services | |
| Elasticbeanstalk and CFN provide functionality which can be utilized by CI/CD servers. |

| What is DevOps? by Rackspace - Really great introduction to DevOps | |

| Sanjeev Sharma series on DevOps (great repetition to really get the DevOps concept) |

| TERMINOLOGY | |
| ----------- | |
| Images - The file system and configuration of our application which are used to create containers | |
| Dockerfile describes an image | |
| Image identifiers can be repo:tag or ID | |
| Containers - Running instances of Docker images — containers run the actual applications. A container includes an application and all of its dependencies. It shares the kernel with other containers, and runs as an isolated process in user space on the host OS. You created a container using docker run which you did using the alpine image that you downloaded. A list of running containers can be seen using the docker ps command. | |
| Image ID != Container ID | |
| When containers are recreated they will have lost any changes made since last created | |
| Docker daemon - The background service running on the host that manages building, running and distributing Docker containers. | |
| Docker client - The command line tool that allows the user to interact with the Docker daemon. |
| Ansible Playbooks | |
| ~~~~~~~~~~~~~~~~~ | |
| As ad-hoc commands are to bash commands, playbooks are to bash scripts. Playbooks run using 'ansible-playbook' command | |
| and not the ansible command. Playbooks are written in YAML. It contain different elements called plays. Plays contain | |
| list of host and at minimum one task. | |
| You can use default host inventory or you can create a new inventory file. | |
| >> sudo su - ansible | |
| >> pwd ==> /home/ansible |
| What is Docker? | |
| Docker is open source project that automates the deployment of applications inside software containers by providing an | |
| additional layer of abstraction and automation of operating-system level virtualization on Lennox seems | |
| DOCKER INSTALLATION | |
| ===================================================================================================================== | |
| Install Docker in CentOS | |
| ~~~~~~~~~~~~~~~~~~~~~~~~ |
I'm using Ansible only for Configuration Management, the server is up and I want to configure users, install packages and configure them.
For infrastructure provisioning terraform.io is nice!
Currently, my deployment flow includes Drone.io/GitlabCI for CI/CD and Docker Swarm for orchestrating containers.
