Ghost image not usable anymore
Hi all,
I just noticed that the "ghost" image is not usable anymore. It will deploy but spinning the pod will fail:

It seems that a running mandatory mysql/mariaDB is hardwired into the images code.
Not sure on how to proceed here.
Either use a different image/app (e.g. nginx, git, hlds ...) or
re-write the helm manifest so a mariaDB will also be deployed or
fix the image so if no DB is available the pod will still spin up ... ?

So, ... since NOBODY replied to my question, I had to figured it out by myself.
So here is the yaml that will deploy a pod with two containers ghost and mariaDB.However, the Pod will come up successfully but will fail (after a minute or so) because mariaDB creates a fresh and completely empty database, thus ghost can't read anything from it.
apiVersion: apps/v1 kind: Deployment metadata: name: sadako spec: # specification for deployment resource selector: matchLabels: app: sadako template: metadata: labels: app: sadako spec: # specification for Pods containers: - name: mariadb image: bitnami/mariadb env: - name: MARIADB_ROOT_PASSWORD value: secret - name: ghost image: bitnami/ghost ports: - containerPort: 80 env: - name: ALLOW_EMPTY_PASSWORD value: "yes"

Hi @mag1,
Would you be able to provide the section in the lab guide where the ghost image is referenced?

I am stumbleing over the same error as @mag1 in the course material. I have jet to view the lab guides. I am following along in the Chapter 11 Ingress of the course in the slide "Creating an Ingress Rule".
It contains the following 2 commands:
$ kubectl run ghost --image=ghost
$ kubectl expose deployments ghost --port=2368The seccond one also fails as the first one does not create a deployment, it only creates a pod.
Hope this helps.
And thanks @mag1 for creating the YAML, will use/replikate it now.Have a nice Easter Weekend!
Best Regards,
McDueerkop

Hi @mag1
Sadly i could not "plug & play" your template into my env.
I always got an error message that the ghost image could not connect to the mariadb instance even though it was running in the same pod.I made some modifications:
- Use the official docker images.
- Pass the development variable into the ghost image, to ensure it starts up as a dev enviornment.
Here is the complete yml for review:
apiVersion: apps/v1 kind: Deployment metadata: name: ghost spec: selector: matchLabels: app: ghost template: metadata: labels: app: ghost spec: containers: - name: mariadb image: mariadb env: - name: MARIADB_ROOT_PASSWORD value: my-secret-pw - name: ghost image: ghost ports: - containerPort: 2368 env: - name: NODE_ENV value: development
Best Regards,

Hi @mag1 and @mcdueerkop,
I would recommend following exercises from the lab guide for hands-on experience. Some of the illustrative commands from the lectures section may not work if applied directly as presented.

-ChrisSee, that's actual the problem. Those exercises include "packages" like ghost and therefore fail without a hint from the text.

Hi @mag1,
Would you be able to provide the lab exercise number and step number where the ghost image is referenced and fails?
Regards,
-Chris0 -
Hi, sorry for the late reply.
Indeed I couldn't find any appearances of "ghost" in any lab-exercise (pdf documents).
But if you go to chapter 7 (Managing State with Deployments) Section: Managing State with Deployments -> Deployment Rollbacks (page: 10) ... here it is used multiple times.0 -
I just hit the same issue. The text of Chapter 11, "Creating an Ingress Rule", sets a clear expectation with the reader that the code presented should work.
To get exposed with ingress quickly, you can go ahead and try to create a similar rule as mentioned on the previous page. First, start a ghost deployment and expose it with an internal ClusterIP service. See the following commands:
$ kubectl run ghost --image=ghost
$ kubectl expose deployments ghost --port=2368
If this should not be taken literally, it should not use literal language issuing directives for the reader to follow along. The fact that this has been a known issue for a year and the paid course still includes the example with the bug is frustrating.
