okay so were going into the Google cloud platform and youre going to want to make your project so when you first sign in its going to ask you for like your email address and then youre going to have to put like a credit card in there for to be able to run your virtual machine in there but theres as you can see here it gives you three hundred fifty days remaining for a full account so it gives you unlimited access so theres a free trial right now but it is gonna charge you something in the future Im not sure exactly what that is yet so thats why its asking for a credit card but after you go ahead and plug that in and put all of that information in and you make your own project you just come in here click new project I already did that chain link node and you can see I have it up here youre gonna go into your compute engine and then the virtual machine and thats what I have right here and youre gonna click create and Im going down through my PDF so I recommend having the PDF on a different screen if you have it or you can print it and you know follow along with it whatever you want it to do but you are gonna have to paste the code so have it open as well so you can copy and paste the code youre gonna come in here and change the name and Im just gonna call this primary chain link node come down here to machine type and youre gonna change this to just the 7.5 and then the boot disk youre gonna change that as well and youre gonna find this 18 0.04 come down here if you have a solid-state drive I really recommend using a solid-state drive if you dont its okay just use the hard drive that you have and itll itll be fine and I recommend starting with about 16 gigabytes for that and then youre youre gonna want to come down here to allow full access to all cloud apis and check this allow HTTP traffic and HTTP traffic youre gonna want to check those click on networking right here expand this part and youre looking for this primary internal IP now I already had one set up but what youre gonna do is youre gonna click reserved static IP youre gonna type in right off of your PDF youre going to type primary chain-link static put in your description which is its a static IP address for a primary chain link node and then click reserved and itll automatically assign it Im not going to do that now because I already have one so Im just going to pick the one that I already have and youre gonna do the same thing for the external youre gonna create the IP address again put in an external static IP put in the description and then click reserved again Im not going to do that because I already have one so Im just gonna select the ones that I have already and then youre gonna come down here and click create and thats going to create your virtual machine that youll actually be able to run that were going to program and code the chain link node on and you can see that that popped up right here so this is the exciting part were going to go ahead and click on this SSH and thats going to go ahead and run our virtual machine here so we can program it ok so youre going to give that a quick minute to just load up and then youre going to copy and paste the very first line of code that I have in the PDF and make sure you copy everything in between the quotation marks if you leave anything off its not gonna work youre gonna get an error and youre gonna have to start over so youre gonna want to copy and paste that in and its going to go ahead and install and this is code that I got directly from chain-link docks Im gonna leave a link there as well so if you want to look at any of the code feel free to check it out okay so you can see that that went ahead and installed now were going to pace the second line of code again make sure to have everything in the quotation marks if you leave anything off youre going to get weird errors its not going to work so just follow along youre going to paste the third line of code now this one has this one has this dollar sign user here I think this is the only time in the PDF that I have this there might be one other place but youre going to want to erase that and type in this name that you have right here so whatever you named this this is what you want to type in here because thats the name of your node so youre going to just type that in and then hit enter and now type in exit and paste the fifth line of code in here and let that create your directory so now now that part is done so were going to need to come back in here and youre gonna go back to your Google cloud again Im going right out right down the line on my PDF youre going to click the navigation menu which is right here and youre looking for sequel SQL so you click on that and youre gonna create an instance and youre going to check this middle one okay so when this comes up youre going to want to type in changeling Postgres and then youre going to want to create a password for that I already have a password for it so Im going to go ahead and select that but youre going to want to type one in or generate one and make sure to write down what that password is youre going to need it later and then youre gonna click create and thats gonna create that this usually takes just a couple of minutes okay so now that thats up and running youre going to see this public IP address youre gonna want to copy that and then from the PDF number six where it starts with where it has that line of code where it has the database URL so once youve copied that over into the database URL code and replaced the public IP address with your actual public IP address thats here and replaced your password for what you just created youre going to go ahead and click on the instance which is right here youre gonna go over right here to connections and youre going to click add Network so now that youve done that you can go ahead and put down a name so youre gonna come over here and type in primary chain link node and then you need to put the external IP in here what I like to do is just duplicate this page and then we can go back and actually pull the external IP we just come over to VM instances and this is gonna be your external IP thats what you want to put there so youre going to copy that over come back to this page and youre gonna paste that external IP right there and youre gonna click done and save okay and once that saves youre gonna come over here to users and youre going to go ahead and create a user and that user is gonna be chain link user and then youre gonna want to pick a password for it Id like to use the same password that I made before click create and this is where you want to replace that password the password that you made for chain link user its the same for me thats why I copied it from before so if yours is different than copy that over here so after youve created your chain link user account youre going to click on databases and youre going to click create database and youre going to type in and chain link and click create and now if you look at the PDF its going to have that line of code that database URL Postgres chain link users gonna have your password your public IP it has the port and it has your username youre going to want to copy that whole line and replace it into that spot that it says paste here so go ahead and replace that spot and then paste that over and then youre gonna hit enter so now that youve pasted it and run that code come back to your compute engine VM instances click on the three dots and click the view Network details and were going to click on this firewall rules and youre going to create a new firewall rule so for the name youre gonna type in chain-link GUI ports its not gonna let me use that because I already have one created but thats what you want to put and thats just your chain link GUI port which has six six eight eight youre gonna come down to targets and youre gonna click all instances in network and now for the source IP ranges youre going to want to open up a new browser and youre going to type in whats my IP address and whatever that comes up is your IP address youre gonna want to paste right here and then youre going to click this TC P and thats where youre gonna put 6 6 8 8 and youre gonna click create click create a new firewall rule chain link database ports then type in your description Postgres database boards 5 4 3 2 and Im getting this directly off that PDF come down to specified targets allow all instances and network again youre going to source that IP its going to be the same you dont have to search it again just type in that same one right in there click the TCP and thats gonna be 5 4 3 2 and youre gonna click create ok so you are now ready to run your node and youre going to paste the eighth line of code in here and click enter and it should install your node its gonna ask for your new password I like to use the same password for everything for the node so Im just going to type that in so now youre going to enter your email address that you would like to use to login to your node with and this can be any email address that youd like okay so lets go ahead and try to log into this node so now youre going to want to type in HTTP colon backslash that external IP that you had here and then hit enter its going to ask you to log in and this is that same email that you used when you created your node once youre able to log in and youre able to see this screen youre going to want to get your Oracle address so youre going to want to come over to fulfilling requests at chain-linked Docs and its just right here under node operators and youre going to click on remix come down to Oracle Sol and youre going to start to compile and Im just going right down this list right here so you run that and then you come down here and youre going to go over to main net and youre gonna copy this come back into remix go to run I should have mentioned this before before we actually deploy the contract and get our Oracle address youre going to want to install meta mask and deposit some ether into the wallet so once youve done that youre going to come over here and this is where youre going to paste this code from a net so just make sure you have that copied over paste that in here and then click deploy click confirm and then youll see this come up and you want to hit confirm okay and you can see that that confirmed so then youre going to want to come over here to the set fulfillment permission and this is where youre going to put your account address so come over into configuration and then copy this over youre gonna paste that and then youre gonna put a comma space true and then hit set fulfillment permission click confirm click confirm and we can see that that confirmed so this is where your Oracle addresses this is very important for you to save this make sure you save this Oracle address youre going to need it so now after youve copied that over youre going to come over to the four swords website and this is going to make you part of the four swords team okay and youre gonna fill in your information the node name that you would like and then your email your requested username your location the languages spoken and we created our node on Google cloud platform and then currently no we are not a review chain link node before swords will help us do that we are and youre going to paste your Oracle address right there and then click Submit Our goal is to create a community of Chainlink node Operators.
