Hi Dan and Stéphane,
thank you very much for the support.
So, what is the solution choice?
Probably, the better choice is `urls` or `mirrors` so it's possible
inside LXD code handle failover with a secondary mirror.
So, for a recap:
Solution a)
{
"datatype": "image-downloads",
"updated": "Sat, 04 May 2013 01:58:57 +0000",
"content_id": "sabayon:images:download",
"products": {
"sabayon:0.1:arm": {
"arch": "arm",
"stream": "devel",
"versions": {
"20190111": {
"items": {
"uec.tar.gz": {
"ftype": "lxc.tar.gz",
"urls": [
"http://mymirror.edu/lxd-images/sabayon/myimages.tar.gz";,
"http://mymirror2.edu/lxd-images/sabayon/myimages.tar.gz";
],
"sha256": "xxxxxx",
"md5": "797e2d488c799eab0a8eb09a9c1ff4a3",
"size": 7314153
},
...
}
>From LXD client-side the logic could be that if `urls` is not empty I
get a random entry from url array and I try to fetch image else use path
field as now.
Solution b)
{
"datatype": "image-downloads",
"updated": "Sat, 04 May 2013 01:58:57 +0000",
"content_id": "sabayon:images:download",
"products": {
"sabayon:0.1:arm": {
"arch": "arm",
"stream": "devel",
"versions": {
"20190111": {
"items": {
"uec.tar.gz": {
"ftype": "lxc.tar.gz",
"path": "/lxd-images/sabayon/myimage.tar.gz",
"mirrors": [
"http://mymirror.edu";,
"http://mymirror2.edu/sabayon/";
],
"sha256": "xxxxxx",
"md5": "797e2d488c799eab0a8eb09a9c1ff4a3",
"size": 7314153
},
...
}
With this solution, `mirrors` contains the hostname with an optional
prefix and from LXD client-side if mirrors have values then a random
field of mirrors field is used and value of path field is used for
creating image URL (mirrors[0]+path)
Please, let me know how we want to proceed so I try to push a PR to LXD
project after my holidays.
Thanks again.
