VM machine Setup

Create a Virtual machine with 4core / 8 GB and 40GB

Host Installation

Starting form scratch we would need to install docker and docker compose.

MacBook-Air-2:~ office$ ssh -i shanaldemo.pem centos@185.93.31.53
[centos@sregistry ~]$ sudo su -
[root@sregistry ~]$ yum update ; reboot
[root@sregistry ~]$ yum groupinstall "Development Tools"
[root@sregistry ~]$ yum install wget
[root@sregistry ~]$ yum install git nginx 
[root@sregistry ~] yum install epel-release

Install Python and PIP

[root@sregistry ~]$ wget https://bootstrap.pypa.io/get-pip.py
[root@sregistry ~]$ sudo /usr/bin/python get-pip.py
[root@sregistry ~]$ sudo pip install ipaddress
[root@sregistry ~]$ sudo pip install oauth2client

Add Docker and Docker-compose

[root@sregistry ~]$ yum install -y yum-utils
[root@sregistry ~]$ yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo
[root@sregistry ~]$ yum install docker-ce docker-ce-cli containerd.io
[root@sregistry ~]$ usermod -aG docker docker 
[root@sregistry ~]$ yum install docker-compose     
[root@sregistry ~]$ service docker start
[root@sregistry ~]# service docker status

[root@sregistry ~]# docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Configration for sregistry setting

There are some setting in the shub and ngnix which we can change to effect the installation. We will change them in these files before we start the application. There are actually only two files you need to change into, generating a settings/secrets.py from the template settings/dummy_secrets.py for application secrets, and settings/config.py to configure your database and registry information.

Secrets

Create a secrets.py file in the shub/setting/ from the template

cp shub/settings/dummy_secrets.py shub/settings/secrets.py

Inside secrets file you want to add a SECRET_KEY.

You can use the secret key generator to make a new secret key, and call it SECRET_KEY in your secrets.py file, like this:

SECRET_KEY="5h1tc_x#3r@5ws7ce-@ci(6b1d-a54xw)!#gkc3ieekswg_@w5"

Select Authentication type

Singularity Registry uses OAuth2 with a token–> refresh flow because it gives the user power to revoke permission at any point, and is a more modern strategy than storing a database of usernames and passwords. A lot of third party Auth option are supports and more can be added.

The preferred auth option is selected in

[root@sregistry sregistry]# vi shub/settings/config.py

# Which social auths do you want to use?
ENABLE_GOOGLE_AUTH=False
ENABLE_TWITTER_AUTH=False
ENABLE_GITHUB_AUTH=True
ENABLE_GITLAB_AUTH=False
ENABLE_BITBUCKET_AUTH=False

we have selected Github auth option for the testing. Which is fast and simple

Create a github account and register application

<todo>

Paste the secrets in the secrates file
