Getting my S2I image in the cluster

[Vishal Biyani]

Hi Everyone,

I have been hacking around with Syndesis and deploying on my minishift cluster. The standard installation and integrations work great. But I am struggling with when I have to customize something in base Syndesis and then install it. Also please feel free to point me to the right place if this is not a place for these questions!

The build itself works great and I can see the images in the namespace

$ syndesis build --app-images --image --flash --project vishal

Now I want to use the images I built with changes to deploy to another namespace but something I am struggling to get right. I don't know if it is something super trivial but let me explain what I tried and triaged so far:

1) I tried installing with syndesis by passing the tag - but it picks up the image from the Dockerhub syndesis repo and does not use the one I build in the previous step

syndesis minishift --install --nodev --project vishal-dep3 --local --tag 1.10.0

2) I noticed that Syndesis calls under the hood syndesis-operator binary[1] so I tried to find the right flags I could pass to the binary. I added an env variable such as FUSE_S2I_IMAGE based on the env variable it adds to the spec[2] but that did not help

3) I tried syndesis-operator binary directly with flags such as --image and --tag and also with --operator-config but they did not seem to help either.

Basically, no matter which method I tried - it was still fetching the syndesis-s2i and syndesis-server images from upstream syndesis docker repo and not from my images built in the previous step. Am I am missing something obvious here?

Hi Vishal,
I think you have two options, pull from images you already pushed to
the different namespace[1], or rebuild and use `--project` to specify
the different namespace to publish images to.

Hi Zoran,

Thanks for the pointers. I was able to build the image and push it to a specific namespace. What I think I am missing is the link to picking up the right image. Apart from imagestream and registry - do I have to change anything to point to my images instead of upstream images?

Hi Vishal,
you also have several options: you can enable development mode on the
operator[1] and make sure your image streams are up to date with your
changes; you can push to a docker registry and reference those tags by
using a custom operator configuration[2].

As always, make sure to look at the DeploymentConfigs and see what
image streams are they pointing to and what those image streams use as
the source.

Hi Zoran,

I tried some combinations and finally got it working - thanks a ton for pointers. I will see if I can contribute the learnings to improve docs or do a simple blog post next week or so.

Thanks
