say_hello('Ira', '😊')

say_hello('Emily','😊')

#keyword arguments

say_hello(emoji='😊',name='Bibi')

say_hello()

Return in python:

How it works:

without return it prints none:

def sum(num1,num2):
    num1+num2

print(sum(10,5))

def sum(num1,num2):

num1+num2

print(sum(10,5))

with return it prints something that I insisted for:

def sum(num1,num2):
    return num1+num2

print(sum(10,5))

def sum(num1,num2):

return num1+num2

print(sum(10,5))

Nested Return:

def sum(num1,num2):
    def another_func(num1,num2):
        return num1+num2
    return another_func(num1,num2)

#should do one thing really well.
#should return something
total=sum(10,20)
print(total)

def sum(num1,num2):

def another_func(num1,num2):

return num1+num2

return another_func(num1,num2)

#should do one thing really well.

#should return something

total=sum(10,20)

print(total)

#issues with print and return

def sum(num1,num2):
    def another_func(num1,num2):
        return num1+num2
    return another_func(num1,num2)
    return 5    #this line will not return because we have already returned something before
    print('hello') #this line will not print because we have already returned something before

#should do one thing really well.
#should return something
total=sum(10,20)
print(total)

def sum(num1,num2):

def another_func(num1,num2):

return num1+num2

return another_func(num1,num2)

return 5 #this line will not return because we have already returned something before

print('hello') #this line will not print because we have already returned something before

#should do one thing really well.

#should return something

total=sum(10,20)

print(total)

Docker to AWS, A journey

Posted on February 17, 2021 | Leave a comment

I am following this lecture to build from here: https://amigoscode.com/courses/631065/lectures/11260263

Docker Image:

Image is a template for creating an environment of your choice, snapshot, has everything to run your apps, OS, software, app code.

Below code we are pulling Apache httpd in docker desktop:

docker pull httpd

1	docker pull httpd

Check the images:

docker images

1	docker images

Run container from this image:

docker run httpd:latest

1	docker run httpd:latest

It will hang up so we write ctrl+c to delete it

we check with this code:

docker container ls

1	docker container ls

docker run

docker run -d httpd:latest

1	docker run -d httpd:latest

we check:

docker ps

docker ps

docker container ls

1	docker container ls

Docker port exposing: before that we are stopping the running container

CONTAINER ID   IMAGE          COMMAND              CREATED              STATUS              PORTS     NAMES
5c14bf083cfe   httpd:latest   "httpd-foreground"   About a minute ago   Up About a minute   80/tcp    objective_roentgen
7c60047c16a0   httpd:latest   "httpd-foreground"   3 minutes ago        Up 3 minutes        80/tcp    intelligent_wiles

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

5c14bf083cfe httpd:latest "httpd-foreground" About a minute ago Up About a minute 80/tcp objective_roentgen

7c60047c16a0 httpd:latest "httpd-foreground" 3 minutes ago Up 3 minutes 80/tcp intelligent_wiles

docker stop objective_roentgen
docker stop intelligent_wiles

Now writing command for exposing the port and running the container:

docker run -d -p 8080:80 httpd:latest

1	docker run -d -p 8080:80 httpd:latest

d for dettach and p for port exposing t

Now the container is running perfectly and exposing the port which we can visit and check with command:

docker ps

docker ps

CONTAINER ID   IMAGE          COMMAND              CREATED         STATUS         PORTS                  NAMES
46077824c7b4   httpd:latest   "httpd-foreground"   3 seconds ago   Up 2 seconds   0.0.0.0:8080->80/tcp   boring_chaplygin

1 2	CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 46077824c7b4 httpd:latest "httpd-foreground" 3 seconds ago Up 2 seconds 0.0.0.0:8080->80/tcp boring_chaplygin

Now going to

http://localhost:8080/

1	http://localhost:8080/

will work perfectly.

It means the container port 80 is exposing to user by port 8080

Now I stopped the container:

docker stop boring_chaplygin

1	docker stop boring_chaplygin

So cannot reach to localhost:8080
Now we want to run in different port we can also follow the step:

docker run -d -p 8095:80 httpd:latest

1	docker run -d -p 8095:80 httpd:latest

Now we can also run multiple containers from a single command:

docker run -d -p 3050:80 -p 8060:80 httpd:latest

1	docker run -d -p 3050:80 -p 8060:80 httpd:latest

We stop and start again the docker container:

docker stop lucid_hodgkin

1	docker stop lucid_hodgkin

docker start lucid_hodgkin

1	docker start lucid_hodgkin

now docker help finding:

docker ps --help

1	docker ps --help

it will show like this:

Usage:  docker ps [OPTIONS]

List containers

Options:
  -a, --all             Show all containers (default shows just running)
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print containers using a Go template
  -n, --last int        Show n last created containers (includes all states) (default -1)
  -l, --latest          Show the latest created container (includes all states)
      --no-trunc        Don't truncate output
  -q, --quiet           Only display container IDs
  -s, --size            Display total file sizes

-l, --latest Show the latest created container (includes all states)

--no-trunc Don't truncate output

-q, --quiet Only display container IDs

-s, --size Display total file sizes

removing a container from here:

docker rm objective_brown

1	docker rm objective_brown

we can show id by

docker ps -aq

1	docker ps -aq

it will show like this:

when we need to remove running container forcefully

docker rm -f container_name

1	docker rm -f container_name

-f for force

Custom name for docker container:

docker run --name website -d -p 3000:80 -p 8080:80 httpd:latest

1	docker run --name website -d -p 3000:80 -p 8080:80 httpd:latest

docker ps

docker ps

Now stopping docker container named website

docker stop website

1	docker stop website

Now running again the docker container:

docker start website

1	docker start website

we check containers with command

docker ps

docker ps

Docker ps formatting:

docker ps --format="ID\t{{.ID}}\nNAME\t{{.Names}}\nIMAGE\t{{.Image}}\nPORTS\t{{.Ports}}\nCOMMAND\t{{.Command}}\t{{.CreatedAt}}\nSTATUS\t{{.Status}}\n"

1	docker ps --format="ID\t{{.ID}}\nNAME\t{{.Names}}\nIMAGE\t{{.Image}}\nPORTS\t{{.Ports}}\nCOMMAND\t{{.Command}}\t{{.CreatedAt}}\nSTATUS\t{{.Status}}\n"

export FORMAT="ID\t{{.ID}}\nNAME\t{{.Names}}\nIMAGE\t{{.Image}}\nPORTS\t{{.Ports}}\nCOMMAND\t{{.Command}}\t{{.CreatedAt}}\nSTATUS\t{{.Status}}\n"

1	export FORMAT="ID\t{{.ID}}\nNAME\t{{.Names}}\nIMAGE\t{{.Image}}\nPORTS\t{{.Ports}}\nCOMMAND\t{{.Command}}\t{{.CreatedAt}}\nSTATUS\t{{.Status}}\n"

docker ps --format=$FORMAT
