Hi @iliemihai :wave:

Have you tried to bootstrap the project without the -k argument?

./bin/arnold bootstrap -c eugene -e development

[iliemihai]

Hello @jmaupetit :D. Yes, I have tried but the problem still persists. I have followed all the steps in README, but when I call bin/arnold bootstrap -c eugene -e development the same error occurs. Can you please help me with a work around. Thank you for you re quick response :)

[iliemihai]

@jmaupetit can you please check if it is reproducible in your environment? I had struggled with this issue for the past 2 weeks :D

[iliemihai]

@jmaupetit I have managed to find the bug, kubernetes 12.0.0 API has a bug in it. It connects to host only on port 80 and it can t connect on local Openshift cluster on port 8443. A workaround is to downgrade kubernetes to version 11.0.0 and openshift 0.11.2. I have tested locally with command ansilbe-playbook bootstrap.yml -e development -c arnold and it worked, but I am having problems running bin/arnold bootstrap -c CUSTOMER -e ENVIRONMENT.

Could someone please help with setting up an Arnold demo with EDX, Richie, Marsha, Joanie, on local Openshift cluster. I am willing to test/update code :D.

[jmaupetit]

We are truly sorry for our outdated documentation. Here is a quick start guide that I hope will help you getting started.

You should first download the latest oc 3.x release we support from its official repository: https://github.com/openshift/origin/releases/tag/v3.11.0

Once installed make sure your version match the following:

$ oc version
oc v3.11.0+0cbc58b
kubernetes v1.11.0+d4cacc0
features: Basic-Auth GSSAPI Kerberos SPNEGO

Once oc is installed, we will use it to start a local OKD cluster using our Makefile ad hoc target:

$ make cluster

You can grab a tea or coffee from here (depending on your configuration, it can take a while to boot).

Once the cluster is up and running, we can deploy our first application using the bin/arnold script:

$ bin/arnold bootstrap -c eugene -e development -a hello

N.B: you may want to deploy another application by changing the -a option, e.g. -a richie.

This is just a quick start guide; from now, I invite you to explore the bin/arnold -h command to explore Arnold possibilities.

Note that we are migrating from Openshift to Kubernetes (see #620). This is a major refactoring of this project. Our objective is to write a complete documentation once this has been merged to the master branch. :crossed_fingers:

I don't know if it's really the place for me to ask my question, but during the same process of running up a dev version of arnold. I end up having some issues when boostraping my cluster, due to arnold requesting my cluster with a self signed certificate (and not ignoring it)

HTTPSConnectionPool(host='10.0.2.15', port=8443): Max retries exceeded with url: /version (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)'),))

Is there a possiblity to ignore the verification, or did I miss something during my bootstrap ? Thansk a lot for your work !

[jmaupetit]

Have you check that the K8S_AUTH_VERIFY_SSL environment variable is defined and set to "no"? Note that it should be defined if you sourced the bin/activate script.

[IDerr]

I did not, but now it is working perfectly ! Thanks for the help :)
