What do I want? It's been a while since I wanted to get into tech. To hold myself accountable in my journey to becoming a DevOps engineer, I have decided to keep a diary. I actually have some little experience programming in python and c++. My post is not going to be about what I'm learning or reading, but, what I'm building, hacks, and my eureka!!! moments. That means my posts are not going to be that frequent. My resources at the moment include this interesting platform [url]kodekloud-engineer.com[/url], Modern DevOps practices(Ebook), and I am also enrolled in the google Africa developer scholarship cloud track. My aim is to build interesting stuff, contribute to open source, have fun, meet cool people along the way, and get a job. 1 Like |

My journey began with containers and Docker specifically. I tried something out that I believe is not only interesting but made me understand more in-depth about containers; docker in docker or rather running docker container in a docker container. it turns out tutorials of this example are actually common out there on the internet. I decided to make mine unique by creating an image that when the container is created from this image it runs a binary file that pulls an image from the Docker repository and runs a container from this so-called "new image", waits for a while, and closed it. Below, I am going to try to do justice by explaining what I did to achieve this. you can also check out the repo here https://github.com/rock16/docker-in-docker-example 1 Like |

first of all, we create a folder like what we have below were dind-example is the root folder, dockerfile is a file that defines our container image,
dockerfile
I used multistage build because I had to compile the go file, and the go file holds the code for pulling down images and creating containers within the container that get spun up from the image we are going to create from this dockerfile. |

I opened my terminal and ran $ docker build -t <dockerhub-username>/<image-name>to create the image next to create a container from the image I ran $ docker run -t --name dindexample0 <dockerhub-username>/<image-name> i got an error the images below shows the error and what I had to do to solve the problem.

what is the use case? sandboxing environment and ci pipeline are some use cases I could remember. sandboxing since containers provide a lightweight environment that is isolated from the host using namespace, cgroup, ability to adjust capabilities, and use of seccomp profile. though virtualization would be preferable over containerization if sandboxing is what we actually want plus my code should be used for experimentation purposes only and not for production. |

brianromel: How much is their training fee? |
| Re: From A Class Teacher To Tech (DevOps) | progress Log by rockok: 9:53am On Dec 10, 2023 |
demmyhandsome:It's free. Though it's likely that one might have to pay for improved experience and things like getting a certificate. |

I am looking for about 5 to 10 people that would be interested in DevOps training for 5 months and commitment fee of #150k . I am not reinventing the wheels as they are tons of free Youtube contents and materials to learn DevOps from. It will be more about production grade projects and exchanging ideas....I don't know everything but I'm in a constant learning mode" My LinkedIn is: https://www.linkedin.com/in/precious-okiemen . I am doing this more for the passion I have for DevOps and the desire to improve myself while also helping others. Feel free to message me on Telegram ( @devopsmaestro_p ) ...if interested. |
