Update supported versions of Docker

[stuclem]

We currently state the following:

vSphere Integrated Containers Engine 1.5 supports Docker client 1.13.0. The supported version of the Docker API is 1.25.

vSphere Integrated Containers Engine 1.5 supports Docker Compose version 1.11.2.

@renmaosheng @zjs @lgayatri @clouderati is this still true? Thanks!

[zjs]

Docker client 1.13.0

Docker client 1.13.0 will be 2 years old when we ship 1.5. It seems like we should consider testing with something more recent. (If not for 1.5, then as a priority for the next release.)

[stuclem]

Thanks @zjs. But, are these still the officially supported versions? I think that @lgayatri tests with something newer, but for 1.4.x I was told that 1.13 was still the officially supported version.

[zjs]

I'm not quite sure how we determine which versions are officially supported. I assumed it was based on what we test, but it sounds like there may be additional factors. @hickeng?

[jitinkumar2018]

ST team is using docker client api version 1.26.

[stuclem]

Thanks @jitinkumar2018, so is that docker client v1.13.1?

Do we have a supported version of Compose that's more recent than 1.11.2? I see that the most recent version is 1.23.1...

[lgayatri]

@stuclem , docker compose version we have is 1.19.

[stuclem]

Thanks @lgayatri.
@renmaosheng, @hickeng and @clouderati, does the fact ST uses these versions mean that we can officially state support for them?

[stuclem]

@renmaosheng according to @DanielXiao in #2218 (review), Photon OS 2.0 no longer supports Docker 1.13, so dch-photon has been bumped up to 17.06 in this release.

If we are advertising that all VIC components are running Photon OS 2.0, and if dch-photon is now running Docker 17.06, isn't it a bit strange that VIC's officially supported version of Docker is still 1.13?

[stuclem]

@renmaosheng says to stick with the current versions in this release. Removing from 1.5.

[lgayatri]

@stuclem, so we will update the newer versions of docker in the release notes?

[stuclem]

@lgayatri, no, we will stick with 1.13 for this release, and possibly update the versions in an update release

[lgayatri]

@stuclem - Ok.
Asked since 1.13 is pretty old version.

[renmaosheng]

we did some test using 17.06 from Yifeng. and found several test failures in CI: so we prefer to update it in next release given the limited time.
This is a full regression test with docker client 17.06 https://ci-vic.vmware.com/vmware/vic/20663/9. 10 tests failed just because of some out put changes.

[lgayatri]

Ok

[stuclem]

According to vmware/vic#8511, the supported versions will be updated in 1.5.3.

[stuclem]

See also #810.

[stuclem]

@vidya-v this is definitely in 1.5.3.

[stuclem]

Looks like vmware/vic#8511 has now been pushed out to 1.5.4.

[stuclem]

According to @luwang-vmware there were issues with the later versions so this is not in 1.5.4.

[stuclem]

@renmaosheng are we going to address this in 1.5.5?

[renmaosheng]

No, we are using the same docker version as 1.5.4, we don't plan to upgrade it. thanks.
