> Docker got updated.

I built my first image locally and now I'm dancing around my desk to myself in satisfaction. I was anxious AF and so that meant I had a million extra questions along the way and everyone helped me. I'm truly grateful. Thanks for teaching me/holding my hand. I can't put into words my gratitude, but truly, thank you so so much.

Was I supposed to clone the GitHub repository before trying to build the image?

I ask because I've just seen these errors

``` => ERROR [2/4] COPY patches/ /tmp/patches/ 0.0s => CACHED [3/4] RUN echo "**** install build packages ****" && apk a 0.0s => ERROR [4/4] COPY root/ / 0.0s ------ > [2/4] COPY patches/ /tmp/patches/: ------ ------ > [4/4] COPY root/ /: ------ Dockerfile:63 -------------------- 61 | 62 | # add local files 63 | >>> COPY root/ / 64 | 65 | # ports and volumes -------------------- ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref 2ad57b92-028a-429f-a2de-be0e9a7f57af::cz3t2511b10hmumww1m73cse6: "/root": not found

```

And being as n00b as I am, I'm instantly trying to attribute the blame to me not doing something.

There's a service that I want to use, however for reasons, it no longer has any builds available. Consequently, I am thinking of building it myself. How does one go about doing that and then afterwards, how do I get it up on Docker hub? Can I just create an account and upload?

If I have

``` version: "3.8"

services: example1: image: example.com/example1:latest ports: 8000:80 volumes:

• shared_example:/data services: example2: image: example.com/example2:latest ports: 8080:80 volumes:
• shared_example:/data

volumes: shared_example: driver_opts: type: nfs o: "192.100.1.100, nolock,soft,rw" device: ":/local/shared" ```

Will that slow things down or is the proper solution to have volumes: shared_example1: driver_opts: type: nfs o: "192.100.1.100, nolock,soft,rw" device: ":/local/shared" shared_example2: driver_opts: type: nfs o: "192.100.1.100, nolock,soft,rw" device: ":/local/shared" Or even volumes: shared_example1: shared_example2: driver_opts: type: nfs o: "192.100.1.100, nolock,soft,rw" device: ":/local/shared"
