kubecrtl is the kubernetes swiss army knife - as well as being able to manipulate kubernetes it gives access to loads of data

But to make use of that data we need to format it - and one of the more powerful ways of doing this is using gotemplates

the help page just says

--template='':
    Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].

which isn’t on it’s own terribly helpful

Connecting Strapi to a Digital Ocean Managed Mysql database required jumping through a couple of hoops

The managed database is available over SSL using a custom CA certificate

In Kubernetes my pod was failing with

env: can’t execute ‘node’: Text file busy

It worked fine locally using docker

JWT uses secrets which are stored securely

This secret is used to sign (opr encrypt) the token - and then the token can be validated using this secret. If the secret is shared between multiple servers - the token can ba validated on any of them.

The secret can change over time (at which point any previous tokens expire) and should be different in each environment eg there is no need to have the same secret in staging and production as token should not be valid across these.

It hasn’t been especially clear to me how a new token is best generated.

The JavaScript ecosystem is a sea of choices and it seems to be all too easy to make an incompatible selection.

In my case I am using the Yarn package manager, the VSCode editor and TypeScript flavoured JS (I don’t think it really counts as a different language)

Every import statement was triggering an error in VScode

Cannot find module ’’ or its corresponding type declarations

Some quick notes on how to debug containers in Kubernetes

If you are running services via docker, how do you make sure they start up after a reboot, after restarting the docker daemon, or just after they crash?

I am working on a postgresql database for a strapi CMS

I’ve taken over the project and when I try and start it I see this error.

create table "public"."strapi_migrations" 
    ("id" serial primary key,
     "name" varchar(255),
      "time" timestamp) 

- permission denied for schema public
