=====Overview=====
OCI or Oracle Cloud Infrastructure is a cloud provisioning by Oracle which offers: PaaS, IaaS and others services.
Firstly, to get access to OCI, we need Oracle account for OCI, which you can create for free at: "cloud.oracle.com"
Like any other cloud infrastructure, there are whole books you can read of the architecture and the processes, but in a nutshell, you can think of it, as something like this:

=====Configuration=====
Once you have your account, your tenancy and your root compartment. It is important to set your configuration.
The "config" file should be in your home location under the .ssh/ folder. Otherwise, you won't be able to connect.
The configuration should have something like that.

<Code:bash|Config file>
[DEFAULT]
user=ocid1.user.__
fingerprint=2d:0d:__
tenancy=ocid1.tenancy.___
region=eu-frankfurt-1
key_file=<path to your private keyfile> # TODO
</Code>

Of course, use yours user and tenancy OCIDs, as well as the private key of the public key you have added as API key.

====Test====
After that, you can test if you are set up, by listing your resources:

<Code:bast|List all instances in your compartment>
(poce_env) julien.andonov@julienandonovs-MacBook-Pro .oci % oci iam compartment list --compartment-id ocid1.tenancy.oc1..aaaaaaaa5ywubcssitfupa2xmwpwng2zms4dt52cw7gsbymr3nxesbkgdgrq

</Code>

There are other commands which you can use as well:

<Code:bash|OCI interface>
###Get Namespace
oci os ns get


#Get tenancy
oci iam compartment list -c ocid1.tenancy.oc1..aaaaaaaa5ywubcssitfupa2xmwpwng2zms4dt52cw7gsbymr3nxesbkgdgrq

###Get Buckets:
oci os bucket list -ns frsg5o7pykju --compartment-id ocid1.tenancy.oc1..aaaaaaaa5ywubcssitfupa2xmwpwng2zms4dt52cw7gsbymr3nxesbkgdgrq

###Create bucket
oci os bucket create --compartment-id ocid1.tenancy.oc1..aaaaaaaa5ywubcssitfupa2xmwpwng2zms4dt52cw7gsbymr3nxesbkgdgrq --name testbucket

###Upload file
oci os object put -ns frsg5o7pykju -bn testbucket --name test.txt --file /Users/julien.andonov/Work/POCE/oci-ansible-collection/samples/compute/launch_compute_instance/test.txt


###List instance based on compartment
oci compute instance list -c ocid1.compartment.oc1..aaaaaaaawmkoyiqsxkalddfg3xxapwk22yovanosn766hjr2xwhk7td7zusa --lifecycle-state RUNNING | jq -r '.data[]."id"'
