By specifying the login data for hub.docker.com you can update the short and
|
||
|
|
long description of a docker repository.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Several options are available to update the descriptions. Either based on
|
||
|
|
Markdown files or as a normal string, which is passed as argument when calling.
|
||
|
|
The examples below describe two ways, the binary and container based way.
|
||
|
|
|
||
|
|
### Example 1: Update full description of the repository with a Markdown file
|
||
|
|
|
||
|
|
```bash
|
||
|
|
dhdu \
|
||
|
|
-user=<username> \
|
||
|
|
-password=<password> \
|
||
|
|
-namespace=<namespace> \
|
||
|
|
-repository=<repository> \
|
||
|
|
-full-description-file=./README.md
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run \
|
||
|
|
--rm \
|
||
|
|
--volume $(pwd):/workspace \
|
||
|
|
volkerraschek/dhdu \
|
||
|
|
-user=<username> \
|
||
|
|
-password=<password> \
|
||
|
|
-namespace=<namespace> \
|
||
|
|
-repository=<repository> \
|
||
|
|
-full-description-file=./README.md
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example 2: Update full description of the repository over an argument
|
||
|
|
|
||
|
|
```bash
|
||
|
|
dhdu -user=<username> \
|
||
|
|
-password=<password> \
|
||
|
|
-namespace=<namespace> \
|
||
|
|
-repository=<repository> \
|
||
|
|
-full-description="My awesome description"
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run \
|
||
|
|
--rm \
|
||
|
|
--volume $(pwd):/workspace \
|
||
|
|
volkerraschek/dhdu \
|
||
|
|
-user=<username> \
|
||
|
|
-password=<password> \
|
||
|
|
-namespace=<namespace> \
|
||
|
|
-repository=<repository> \
|
||
|
|
-full-description="My awesome description"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Compiling the source code
|
||
|
|
|
||
|
|
There are two different ways to compile dhdu from scratch. The easier ways is
|
||
|
|
to use the pre-defined container image in the Makefile, which has included all
|
||
|
|
dependancies to compile dhdu. Alternatively, if all dependencies are met,
|
||
|
|
dhdu can also be compiled without the container image. Both variants are
|
||
|
|
briefly described.
|
||
|
|
|
||
|
|
### Compiling the source code via container image
|
||
|
|
|
||
|
|
To compile dhdu via container image it's necessary, that a container runtime
|
||
|
|
is installed. In the Makefile is predefined docker, but it's can be also used
|
||
|
|
podman. Execute `make container-run/dhdu` to start the compiling process.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
make container-run/dhdu
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Compiling the source code without container image
|
||
|
|
|
||
|
|
Make sure you have installed go >= v1.12. Execute `make dhdu` to compile
|
||
|
|
dhdu without a container-image. There should be a similar output as when
|
||
|
|
compiling dhdu via the container image.
