Example containers using old images

[allentc]

Some of the images that appear in example/docker-compose.yml are very old. Example:

• prometheus v2.25.0 (2021-02-17)
• grafana 7.3.7 (2021-01-14)
• etcd 3.4.15 (2021-02-26)

I'd offer a pull request to update images but I haven't found any compatibility matrix or other information on what has been qualified for use with APISIX.

@navendu-pottekkat can you have a look at this please? I'm also curious whether we have a set of updated images for the same which will be potentially used as a replacement?

[pottekkat]

@Neilblaze Thank you for the ping. @allentc Thank you for opening this issue.

@Neilblaze yes, these could be updated. I think we can use the latest LTS versions of each of the images. Prior to making a pull request, please test and check if everything is working as intended.

We can use the existing images but bump the version. I don't there would be anything else to change but look out for compatibility issues.

Prometheus & Grafana are for the all-in-one case, +1 to upgrade them, but do we really need a all-in-one sample docker compose?

[soulbird]

I don't think all-in-one has any effect, we can consider deleting it

[Neilblaze]

I'm a bit confused about whether to remove Prometheus and other images entirely from the compose file. Would you mind sharing some light on this? And else, if I want to upgrade them in general, where can I get the latest images that would be used as potential replacement?

, if I want to upgrade them in general, where can I get the latest images that would be used as potential replacement?

To confirm: "them" - do you mean Prometheus, APISIX, and other components?

For this issue, welcome to file a PR to upgrade them.

@Neilblaze You can use the later versions of the same images from Docker Hub.
