Introduction
this is part 22 from the journey it's a long journey(360 day) so go please check previous parts , and if you need to walk in the journey with me please make sure to follow because I may post more than once in 1 Day but surely I will post daily at least one 😍.
And I will cover lot of tools as we move on.
useful commands
this is a contd... for last part , I will talk about some useful commands that you may use on daily basis with docker-compose.
first let's stop all containers with
docker container stop $(docker container ls -a -q)
now let's say we need to run only PostgreSQL without Django image , we can do this by
docker-compose -f local.yml up postgres
postgres here is the name of the service.
We can see that PostgreSQL run without Django because in our local.yml it doesn't depend on Django.
In other hand in local.yml we have Django depends on postgres.
so when I try to run Django postgres will automatically start also.
docker-compose -f local.yml up django
So in case in our development Database got stuck or whatever we can restart database only using
docker-compose -f local.yml restart postgres
and this will make it restart.
Exec
In case you need to interact with docker container you can use
docker-compose exec sh
In my case in Django sometimes I need to used python shell to create Objects and feed them to Database.
I can access python shell in same way
docker-compose exec python
actually you can do what ever you want with exec like run a script inside the folder.
Let's take example you have a script that load fake data to database.
