# Working notes for pushing images to Docker Hub

> Note: It appears that the personal accounts on Docker Hub no longer automatically build based on a Github repository being tagged. (Maybe they never did as it's been 4 years!)

## Built and Tag

This created the `latest` tag:

```bash
$ docker build -t a2geek/cc65-pipeline .
Sending build context to Docker daemon  135.2kB
Step 1/5 : FROM alpine:latest
 ---> e7d92cdc71fe
Step 2/5 : LABEL description="This is a cc65 Docker container intended to be used for build pipelines."
<snip>
 ---> 207cf150f1f0
Step 3/5 : ENV BUILD_DIR="/tmp"     CC65_VERSION="V2.19"     NULIB2_VERSION="v3.1.0"     AC_VERSION="1.7.0"     BASTOOLS_VERSION="0.3.1"     ASU_VERSION="1.2.1"

<snip>

... and this tagged it with the date:

```bash

```

Check:

```bash
$ docker images
