Name: "upgrade",

Aliases: []string{"u"},

Usage: "Upgrade recipe image tags",
|
|
Description: `
|
|
This command reads and attempts to parse all image tags within the given
|
|
<recipe> configuration and prompt with more recent tags to upgrade to. It will
|
|
update the relevant compose file tags on the local file system.
|
|
|
|
Some image tags cannot be parsed because they do not follow some sort of
|
|
semver-like convention. In this case, all possible tags will be listed and it
|
|
is up to the end-user to decide.
|
|
|
|
The command is interactive and will show a select input which allows you to
|
|
make a seclection. Use the "?" key to see more help on navigating this
|
|
interface.
|
|
|
|
You may invoke this command in "wizard" mode and be prompted for input:
|
|
|
|
abra recipe upgrade
