WIP: Add up and down command/scripts and make portainer optional

[chregu]

Needs #1 first merged, therefore WIP for now

• add scripts/pontsun up and scripts/pontsun down
• makes portainer startup optional via .env
• Manual docker-compose up still works

[Aerzas]

I'm not sure if we should abstract docker-compose which is already an abstraction of docker. Templates and commands are quite straightforward.

Portainer is already marked as restart: unless-stopped which would prevent it from starting if stopped.

[chregu]

Yeah, for portainer maybe not. But there's more services in future to be added. A dnsmasq service eg. is not needed on all setups and also the ssh-agent service may only be needed on OS X (and maybe windows). So I'd like to have a better scriptable "up" command.

But sure, the portainer thing is quite optional. And I'd also like to keep this "up" command optional, more of a helper for getting pontsun getting started faster for non-experts with some checks (like the .env check)

And as long as "docker-compose up" still works, I don't see how such a script hurts.

[NITPICK] Please use >&2 at the line start, to output to stderr, not stdout.

[chregu]

Sure, changed.

[chregu]

Also that I can do

$PATH_TO_PONTSUN/scripts/pontsun up

from any place and not need to do

cd $PATH_TO_PONTSUN/containers && docker-compose up -d
cd $BACK_TO_WHERE_I_WAS

which is much easier to remember, type, use-in-other-scripts

[Aerzas]

I mean we could achieve the same results with multiple docker-compose.yml files like docker-compose -f docker-compose.yml -f docker-compose.dnsmasq.yml up -d so options are explicit and yet we don't create an abstraction layer.

My opinion is that we should ease the setup of local dev environment without replacing docker or docker-compose or maybe in a separated project.

Moreover, we'll probably execute this command once or twice to mount it once and it will remount at every startup automatically.

[chregu]

Ah, didn't know you can have more than one -f, good then.

We seem not to agree, what this project should include and what not. So let's create a pontsun-cli project and move what my vision of this "cli" is there and leave this here pure.

[chregu]

Obsolete. That stuff will go into a new project.
