Docker compose CLI

    I was surfing on the internet but could not find a good tutorial on content which will help understand the usage of the docker compose cli commands. Now the question is if we have a docker desktop why should we learn cli commands ? It is because now that we are seeing a lot of left shifting of the responsibilities on the developers including DevOps. Hence we should know how to manage, debug and check the environment servers which may not have a docker desktop sort of GUI. Another question would be if we have docker cli commands then why should we learn the docker compose cli commands ? It is because docker cli commands are more general level and docker compose commands work at a docker compose level. Meaning a folder which has a docker-compose.yml file. The docker compose CLI commands are applicable for that scope. Another reason is it simplifies the services and container management at the compose level. One key point to be noted is we should remember the fact that docker compose containers and services (i.e. the ones defined in the docker-compose.yml file) run in an isolated scope hence service container A defined in docker compose yaml file A cannot directly interact with the service container B defined in the docker compose yaml file B.

    I will be documenting my learnings as step by step tutorial guide for you to understand and use the same. I will be doing so while I am learning these commands so that it is shared experience for a new person.

Container detached from docker network

Introduction One fine day you find out that one of your docker containers is running but is not currently attached to the container network that you created using docker network command. Ideally a container should be detached from the network when there is some error in it. However, if you set the restart: on-failure in the docker-compose.yml  in that case the container should restart and still be attached to the network. In such a weird situation follow the steps documented in this blog. Possible reasons Listed below are the possible reasons for this issue Storage space issue Memory issue ( We will cover this in next blog ) Storage space issue We need to check the space utilisation at the server level first then drill down to the docker engine. Server level utilisation In most cases the server is ubuntu system hence check the disk usage using the disk free command (i.e. df -h ). It will show you the current storage space utilisation of the server. df -h Docker engine space utilis...

Secure login to MySQL for bash scripts

Introduction In this blog we will connect to a mysql via CLI from a bash script for generating a db dump. A cleaner approach for the same is using mysql config editor. In this blog we are taking an example of a mysql container running inside docker and we have a script for taking a db backup using  mysqldump . We will not use a password as a parameter to  mysqldump  command instead we will use something called as login path. MySQL config editor It is a utility to store authentication credentials in a obfuscated login path file named as  .mylogin.cnf . How to do it ? View existing configurations To view existing configurations if there are any use below command. The command will output existing configurations if there are otherwise it won't print anything. mysql_config_editor print --all Sample output In the output below you can see that the password is obfuscated and is not readable directly. It is handled by the mysql utilities to use this password as per the flags ...

TOP down or bottom UP approach to Learning

      All of us have unique learning ability. Learning new thing has two of many approaches ( i.e TOP-DOWN or BOTTOM-UP ). TOP down approach is from Generalisation to Specialisation approach and BOTTOM up is inverse. Which approach to follow depends on the individuals choice and level of experience. In both the cases you can start small then broaden your learning and then narrow it down for easier storage and retrieval. Let's do a comparative analysis today of these approaches and understand which approach is better.     Learning something new requires lot of efforts and if you do it wrong then you tend to confuse yourself and lose confidence. Let's take an example of the BOTTOM up approach, if you are learning a new programming language and you start with the datatypes, reserved keywords, access specifiers, etc. then you will need more efforts to first store all what you learnt then club them together to create a logical whole. Most of us will argue s...
