Maybe I think ECS task cannot access to outbound.
When I execute apt-get update, it throw errors.

This link may help. Either the server is dead or ipv6 isn’t working properly.
IPv6 Network is unreachable (os error 101)
Edit: You can try and add ipv6.disable=1 to the GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX entries in /etc/default/grub.cfg then run sudo update-grub. This way it will default to ipv4 and work properly.

I modified the code to work. I identified that the main issue is mongodb-clients which causes failures of monogdb. Also your command db.createUser is invalid and will lead to failure as well. I did not fix that, as its not related to your issue about connection refused. You can make new question why your db.createUser is incorrect (I don't know how to fix that, its mongodb specific).

Isn't brew the command, and services only a parameter? I am not understanding why the error says that services is an unknown command. Thank you.
UPDATE 1: I see two warnings when I try to run brew install mongodb-community#4.2 again. Maybe that has something to do with the problem?:
jaimes-mbp:SMR jaimemontoya$ brew install mongodb-community#4.2
Warning: mongodb/brew/mongodb-community-4.2.3 already installed
Warning: You are using OS X 10.15.

Maybe I do not need to use brew services start mongodb-community#4.2? I thought it was necessary to run MongoDB Community Edition.
UPDATE 3: I run ps aux | grep -v grep | grep mongod and it returns nothing. I am trying to verify that MongoDB is running, so I am searching for mongod in my running processes but it returns nothing, meaning that MongoDB is not running I guess.
UPDATE 4: See what happens when I run brew doctor --verbose:

Seems like you are facing issue with brew.
Run brew doctor --verbose to check if the brew is working fine.
And then brew update to update the brew version.
After this run, brew services list to display all the services in the brew.
If you see mongodb-community#4.2 there in the list, then run brew services start mongodb-community#4.2
It should work.
I followed the advice MikeMcQuaid provided at https://github.com/Homebrew/brew/issues/3665:
You need to uninstall and install Homebrew using
https://github.com/Homebrew/install
As explained at https://github.com/Homebrew/install, I first ran /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)". After that I ran /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)".
Then I ran this:

I tried the suggested fix missing too but didn't work.
How can I install a postgresql package successfully? And mainly how can I get the $psql command to give me the desired output showed in the picture?
(Edit) I tried the first answer's suggestion:
vagrant#precise64:~$ apt-get update
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Then tried the solutions mentioned here :

vagrant 1144 0.0 0.2 11676 948 pts/0 S+ 18:59 0:00 grep --color=auto apt
I don't understand so I don't know what's next.
looks like you had some trouble installing several packages 404 Not Found.
Do sudo apt-get update and then retry the install.
I'm trying to upgrade postgres locally so I don't get a version mismatch error. This is what i do:
echo "http://dl-5.alpinelinux.org/alpine/v3.5/main" >> /etc/apk/repositories;
apk update
bash-4.3# apk add postgresql-dev
(1/4) Installing libressl2.4-libtls (2.4.4-r0)
(2/4) Installing libressl-dev (2.4.4-r0)

(4/4) Installing postgresql-dev (9.6.5-r0)
Executing busybox-1.24.2-r13.trigger

bash-4.3# pg_dump
bash: /usr/bin/pg_dump: No such file or directory
I'm at a loss - any idea what the problem is please?
Just a guess but I guess you've not installed postgresql. In order to use the pg_dump you must have installed this, or if you do have it already and I'm wrong try reinstalling it like so:
bash-4.3# apk del postgresql

As you can see from above pg_dump is working because it is in the postgresql package even though as listed on alpine packages site it should be within the postgresql-client package as shown here but it doesn't work unless postgres is installed. If you can't have a full postgres installation, I recommend this workaround which is a bit unclean, install postgres, backup the pg_dump binary, uninstall postgres then restore pg_dump like so:
bash-4.3# apk add postgresql
(1/2) Installing libxml2 (2.9.4-r4)
(2/2) Installing postgresql (9.6.5-r0)

bash-4.3# cp /usr/bin/pg_dump /usr/bin/pg_dump.back
bash-4.3# cp /usr/bin/pg_dumpall /usr/bin/pg_dumpall.back
bash-4.3# apk del postgresql

It is not ideal but it has worked for me in the past
