to deploy this rail 7 application to heroku and yeah so let's get into it actually i'm going to start off on the heroku dashboard here i'm going to say new we're going to create a new app it's just going to be called i don't know creator platform demo and we're going to say create app now there's a couple different ways you can deploy you can connect directly to a github repository now every time the github repo every time you push to a certain branch on the repo then it'll auto deploy that's pretty cool and that's actually usually the way that i do it but today what we're going to do is use git heroku get and since we already have an existing repository it's as easy as this one liner calling heroku get remote and adding like so so we're going to say heroku git colon remote dash a creator platform demo and this is going to set up a remote for us so if we say git remote dash v now we have this new heroku remote and what we can do is say git push heroku main and that is going to push our rails application from where it is locally up to uh up to heroku now our first push we see that this failed and this is confusing if you run into this for on your first push and you're on an m1 double check to make sure that you have run this command which is bundle lock ad platform x86 64 linux and what this will do is just it's just going to add a couple other dependencies to your gem file that lock so if we look at the git diff here there's now like a nokogiri for different versions and now we see this platform is here that's because i'm on an m1 but heroku is still running this x86 64 sort of linux box so we'll say git add a git commit um use x64 i don't know get push heroku main and we cross our fingers and hope that it all works right okay so usually this is sort of a game of trial and error i'll push see what's going on and then wait and then do it again but um yeah hopefully we're going to save you some of those steps by watching this episode all right it looks like it failed again so let's scroll up and look at the errors it says no method to find square bracket for nil class here so if you get this error rail's rails.application.credentials.stripe with this thing or any secret for that matter it's probably because heroku does not know how to decrypt your secrets so what we want to do is uh our master key so we're going to say uh we're going to set a new environment variable on heroku by doing heroku config colon set and the value is going to be in this file called config master key now this master key is something you should never commit to get it is something that you definitely want to keep secret and it is the thing that is used to decrypt all of your secrets so i ran it right there i'm gonna blur out the key so you can't see it and decrypt all this stuff because we don't have any changes on our local branch one way we can attempt to have heroku rebuild is by saying heroku restart so after we change an environment variable usually the app will restart but if we say heroku logs t right now this doesn't it's not going to re-kick off another build right and so what we want to do is actually manually redeploy this so one option is to just say git commit dash dash amend dash no edit and then get push heroku main all right so this is going that's just going to create basically like an empty commit that changes the i don't know what's what's in there we pushed again and now we just wait with our fingers crossed and baited breath all right hey it looks like things may have happened successfully it looks like verifying deploy is done so what we can do now is say heroku open and again we sort of cross our fingers and hoping that oh no sorry where something went wrong okay so heroku logs dash t and let's see what's going on here okay uh active record statement invalid pg undefined relation stores does not exist so we have that recall that we have that domain constraint the domain routing constraint and so the very first time it attempts to use uh a query against an active record it's failing that's because we haven't migrated the database if we look up higher too at the end of the deployment output it told us no proc file detected using the default web server we recommend explicitly declaring how you want to boot your processes via a proc file so what i want to do is create a proc file now a proc file lists out all the different process types and the command to start that process so we're probably going to have a web process and we're probably going to have a worker that's going to be our sidekick worker so web is going to be bundle exec puma dash t5 colon5 we wanted to use port 3000 unless the environment variable for port is defined and then we're gonna say use the rack for the worker we want to start up sidekick so we're gonna say bundle exec sidekick dash c2 that just defines the concurrency you could also pass in like the config sidekick dot yaml file thing here with i think it's dash c um i think just dash c2 works just fine now one other pro tip is that in your proc file here you can have a release uh a release process type and the release process type is something that will happen at the end of at the end of your push or the end of your deploy and so this is where i like to put bundle exec um rails db migrate that'll run all of our migrations so we're going to say git add git commit add proc file push it up to heroku and again we wait awesome so at the end of the build output you can see all of the migrations are running so that's super uh super handy okay so now let's see if it's working so we refresh and we now have an application error okay so heroku logs dash t and let's see what it's complaining about now app crashed no application configured nothing to run status whatever okay so let's see what's going on here so we see build started at the end let's try heroku restart i had a mistake in the proc file it should have had a dash in front of the 3000 let's see if that's what's going on okay so yeah now in the build output we can see the proc file declares these types of processes so release web and worker and okay so now let's see heroku logs dash t all right starting to up all right so now we should be able to refresh this amazing okay we see our page that's fantastic all right so if we were to now attempt to register we'll just say like test at example.com password password and hit sign up look at that welcome you successfully signed up so if we go to our dashboard we would need to create a stripe account since you've seen the stripe connect onboarding a few times i'm going to run through the flow and we'll jump back after we have onboarded our stripe account all right we're back and we have an account that is all activated that's looking great let's see if we are able to use our products creation so we're gonna say test test and then pick a cover photo for the product and enter in some amount and click create product oh no okay we've got an error so we're going to go back out heroku logs dash t let's take a look at the server logs and see what's going on okay we have actually a couple errors failed in queueing active storage analyze job with sidekick so we weren't able to actually add a job to the background with sidekick so that is something we can fix so we want to say heroku add-ons create heroku-redis this is going to add the redis add-on you can see which add-ons you have by running heroku add-ons and that'll give you sort of like the list of all the add-ons you're using so we're using the postgres add-on for our database and we're using the redis add-on the redis add-on is going to be used again sort of just in the background for our background jobs notice that the state of heroku redis is still creating so we need to wait for that redis sort of instance to be fully created before we'll be able to connect to it so we can run this just a few times and check on the status but that heroku redis instance needs to be fully up and running before we can actually attempt to create a product we can also run heroku add-ons weight heroku-redis just to see when this thing is actually going to be ready so it's creating creating creating creating creating and we can just sit here and wait till it's done i got impatient and thought that it might be broken and so i tried to create another one but i should have just waited boom we have it okay that actually took like six minutes seven eight i don't know but okay so now when we run heroku logs dash t we should see some logs that look happier for us when we try to submit a product refresh resubmit uh all right download key from here uh another internal server error okay internal server error but why what is the error now okay great okay could not open library libvips.so.42 cannot open a shared object file no such file or directory this error is because we need that vips thing vips that's the image it's the library that does our image processing and by default we when we were working locally we brew installed vips right but when we're on heroku we need to add a build pack in order to make this work so we can say heroku uh build packs colon add index one this says add the build pack at the very beginning i know i don't know why it's one index instead of zero index like this is a computer science platform people okay and then we're gonna say heroku dash community slash apt this is gonna allow us to install packages with apt so now we have two build packs we have heroku community apt we have heroku ruby now apt lets us create an apt file and tell it which packages we want to install with apt these are the ones you need for working with uh vip with vips i guess okay um or actually no those are the dependencies for this other build pack so we have to add another build pack here so it's gonna say heroku build packs colon add index two now this build pack is provided by someone brandon cc thank you brandon cc everyone owes you a debt of gratitude so brandon cc built this heroku build pack for vips and we want to add that at index 2. so now we have apt at the top we have this other build pack and then the final build pack whatever is the last build pack that's going to be the build pack that's used to automatically derive which procs to run and things like that so we've got now a an apt file we need to commit this get pusher roku main and then again we wait heroku let's run the heroku logs again try our submission again with our image cross our fingers and hope that it works okay no errors redirected to this thing boom look at that okay we have an image this image was uploaded successfully from heroku to s3 we can head over to s3 here and see some new i don't know some new object that was just added so this is today okay so we have a brand new image we all of these are the same image basically so it's going to be hard to tell or it's like the same two images so that allows us to upload images to heroku so now we've got an app that's being deployed the the next step is to set up our domains so come back in the next episode and we're gonna set up cloudflare domains we're going to set up ssl we're going to have a fully connected ssl thing with our custom domains and all of that using cloudflare to terminate ssl with a wildcard domain and then we're going to have ssl setup an origin cert between cloudflare and her it's going to be great come back for the next episode thank you so much for watching i really appreciate it if you're finding this video useful give it a thumbs up that'll help
