# Description
25
26
This script automates the process of building and pushing a Docker image to DockerHub, while incrementally tracking the version number. It uses the directory name as the default local image name, but allows for customization through command-line arguments.
27
f5ad62 Tebby Dog 2025-07-06 23:35:18 28
The script builds the Docker image with a version tag in the format `MM.DD.YY.<counter>`, where `<counter>` is an incremental value stored in a file. The image is then tagged with additional tags on DockerHub (`latest` and `<dockerhub_repo>/<image_name>:<date>.<counter>`).

# Usage
14246b Tebby Dog 2025-07-06 21:26:59 31
32
To use this script, save it to a file (e.g., `build_and_push_docker_image.sh`) and make it executable by running `chmod +x build_and_push_docker_image.sh`.
33
34
You can run the script in three different modes:
35
36
1. **No arguments**: The script will use the directory name as both the local image name and Docker image name.
37
```bash
38
dcp
39
```
40
2. **One argument**: The script will use the parent directory name for the local image name, but allow you to specify a custom Docker image name using the first command-line argument.
41
```bash
42
dcp <DOCKER_IMAGE_NAME>
43
```
44
3. **Two arguments**: You can specify both the local image name and the Docker image name as separate command-line arguments.
45
```bash
46
dcp <LOCAL_IMAGE_NAME> <DOCKER_IMAGE_NAME>
47
```
48
49
# Example Output
50
51
When you run the script, it will output something like this:
52
```
53
Docker image built with tag: myimage:02.14.21.1
f5ad62 Tebby Dog 2025-07-06 23:35:18 54
Docker image tagged: <dockerhub_repo>/myimage:02.14.21.1
55
Docker image tagged: <dockerhub_repo>/myimage:latest
56
Docker image pushed: <dockerhub_repo>/myimage:02.14.21.1
57
Docker image pushed: <dockerhub_repo>/myimage:latest
14246b Tebby Dog 2025-07-06 21:26:59 58
59
Local Image Name: myimage
60
Docker Image Name: myimage
61
```
62
Note that the exact output may vary depending on your directory name and DockerHub credentials.
63
64
# Assumptions
65
66
This script assumes you have Docker installed on your system, as well as the `docker` command in your PATH. Additionally, it requires a valid DockerHub account with access to the repository where you want to push your image.

# Setting up an Alias
167
168
To make it easier to use this script, you can set up an alias by adding the following line to your shell configuration file (e.g., `~/.bashrc` or `~/.zshrc`):
169
```bash
170
alias dcp='/opt/dcp/dcp.sh'
171
```
172
Once you've added this alias, you can simply run `dcp` instead of typing out the full script name.
173
174
# Using the Alias
175
176
To use the `dcp` alias, simply type:
177
```bash
178
dcp [optional arguments]
179
```
180
For example:
181
```bash
182
dcp myimage latest
183
```
f5ad62 Tebby Dog 2025-07-06 23:35:18 184
This will build and push a Docker image with the tag `<dockerhub_repo>/myimage:latest`.
