## Dependencies:
|
|
Running docker (duh) and compose, either standalone or plugin.
|
|

The script will ask to download `regctl` if it's not in PATH or current directory.

## `dockcheck.sh`
|
|
```bash
|
|
$ dockcheck.sh -h
|
|
Syntax: dockcheck.sh [OPTION] [optional string to filter names]
|
|
|
|
Options:
|
|
-h Print this Help.
|
|
-a Automatic updates, without interaction.
|
|
-n No updates, only checking availability.
|
|
```
|
|
A script to check for updates on all currently running containers without pulling images, list them and give the option to update.
|
|
|
|
Basic example:
|
|
```bash
|
|
$ dockcheck.sh
|
|
. . .
|
|
Containers with updates available:
|
|
whoogle-search
|
|
|
|
Containers on latest version:
|
|
glances
|
|
homer
|
|
|
|
Do you want to update? y/[n]
|
|
y
|
|
```
|
|
Then it proceedes to run `pull` and `up -d` on every container with updates.
|
|
|
|
|
|
|
|
And with `-n No updates` and `gl` for *gl* filtering:
|
|
```bash
|
|
$ dockcheck.sh -n gl
|
|

|
|
glances
|
|
|
