How to install Google Cloud SDK in CentOS6 without breaking things

 

The long and short of it is that Python 2.6 is no longer supported. While RedHat will obviously continue to backport security fixes for a while, developers have to also consider this when they write their code. RHEL/CentOS are consumed by people who dont want the rug pulled out from under them with a huge change. Upgrading from Python 2.6 to 2.7 can actually break some things. As such, they likely wont ever upgrade it within version 6.
 

Okay, so I just can’t use the google cloud sdk in CentOS6? I didn’t say that. Besides, I am always up for a challenge.
 

We have a few options here.

  1. We can upgrade the system Python from 2.6 to 2.7 and cross our fingers.
    • This usually isnt a realistic option for most businesses. The reason being, the outcome is kind of unpredictable. It all depends on what you have installed, and whether it will work under Python 2.7.
  2. We can install the Python 2.7 binary with an alternate name.
    • This is a pretty good alternative, and it gets us about half way there. But we just need to be able to ensure we dont cross our libraries between the two versions. There has to be a better way.
  3. We can install it in an alternate location entirely, and use our bashrc to change it per session.
    • This seems like the ideal solution. Our changes will only exist within our sessions, and we install in an alternate location. We can make it relatively permanent by putting it in our users .bashrc.

Since we are going with option 3, we need to start by installing the EPEL Repository. Then, using the EPEL Repository to install the CentOS-SCL Repository. From there, we can install the SCL build of Python2.7, which will put it in /opt, with a rather clever way to enable it.

Make it permanent for our user

Now that python2.7 is installed. We need to set some variables to actually use it when we login. Note, we have not changed the rest of the systems default python. Our install went to /opt/rh/python27.

In your .bashrc, put the following:

. /opt/rh/python27/enable
export set CLOUDSDK_PYTHON=/opt/rh/python27/root/usr/bin/python2

Now you can either log out, and log back in for it to take effect, or you can just type ‘source ~/.bashrc’. This will reload your .bashrc along with our new variables.

Install Google Cloud SDK

now lets follow the directions from google… kind of. https://cloud.google.com/sdk/docs/downloads-yum

tee -a /etc/yum.repos.d/google-cloud-sdk.repo << EOM
[google-cloud-sdk]
name=Google Cloud SDK
baseurl=https://packages.cloud.google.com/yum/repos/cloud-sdk-el7-x86_64
enabled=1
gpgcheck=1

gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
       https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOM

this will add te google-cloud-sdk repo. Unfortunately we cant just yum install it. Take a look:

Wait, I thought we had python 2.7 installed? Well, we do.. But its called python27, and the actual “python” package installed is still 2.6. So RPM thinks this would be incompatible. Although, if we work with RPM directly we can ask it to just trust us. So lets grab the RPM using yumdownloader(yum install yum-utils).

We used yumdownloader to actually download the google-cloud-sdk rpm from their repository.
It is imporant that you have set your environment variables at this point, to enable the SCL version of python. If you have not, this next part will fail.

We used rpm to install the .rpm file we downloaded. We used –nodeps to tell rpm not to worry about the dependencies. Make sure to only use “–nodeps” when you know what you are doing.
 

Authenticate and test

Now let give it a try to make sure it works.

First, you authenticate, it will give you a URL. You visit that URL and log into your google account. This returns a code that you then provide to the gcloud CLI to authenticate you.

[root@c95d49d56cde /]# gcloud auth login 
Go to the following link in your browser:

    https://accounts.google.com/o/oauth2/auth?redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&prompt=select_account&response_type=code&client_id=0000000000.apps.googleusercontent.com&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcloud-platform+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fappengine.admin+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcompute+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Faccounts.reauth&access_type=offline

WARNING: `gcloud auth login` no longer writes application default credentials.
If you need to use ADC, see:
  gcloud auth application-default --help

You are now logged in as [thisisclearlyfake@gmail.com].
Your current project is [None].  You can change this setting by running:
  $ gcloud config set project PROJECT_ID
[root@c95d49d56cde /]# 

Now lets set our project to be default:

[root@c95d49d56cde /]# gcloud config set project test-project
Updated property [core/project].
[root@c95d49d56cde /]#

And last, lets confirm we can list the instances to make sure it works.

[root@c95d49d56cde /]# gcloud compute instances list
