vSphere Integrated Containers 1.4 – Upgrade 3/3


Finally, we get to the last step on this journey of upgrading my environment to the latest and greatest vSphere Integration Containers so far.

Today I'll upgrade my Virtual Container Host, VCH, to version 1.4

VCH management and lifecycle actions, like upgrades, are performed through the use of VIC Engine Bundle.
If you haven't that available yet or is using an older version, grab it now.
Engine Bundle can be found on the VIC Getting Start page (https://VIC:9443)

Unpack the binaries from Engine bundle tar file;
Run: tar -zxf vic_1.4.0.tar.gz

Check the VCH version on your environment;
Run: vic-machine ls
As you can see it's running version 1.3 and has one container running.

The amazing thing about VIC is that interruptions, like upgrades, to VCH, does not cause any outage to the containers, basically because they are running independently as container-vms;
if you are using NAT based port forwarding then communication will be briefly interrupted but if you are using the exclusive VIC feature, Container Network, you are in good shape them.

Now that we know the ID of our VCH we can upgrade it.
Execute the vic-machine upgrade command and specify the VCH's ID we just got from the previous step.
Run: vic-machine upgrade --id "VCH_ID"

In less than 3 minutes my VCH has been upgraded to version 1.4 and as you can see my container kept running for the entire process.


WHAT ABOUT MY CONTAINERS ???

There's no process to upgrade your running containers !!!
Containers are ephemeral by nature, so if you want a newer version, delete it and create a new one. Welcome to the container world !!!!

VIC containers are based on Photon OS, and with VIC 1.4 comes a new bootstrap.iso version; don't get too excited, it was not this time it got upgraded to version 2.0, but it got some nice minor packages updates.
So any previous container will still be running the old Photon OS version but the new ones will get the new bootstrap.iso version.

For comparison, I just run a new container based on the same image and compared the OS versions.


That's all folks there are no more excuses to be running an older VIC version if you still unsure about why to upgrade, take a look at the complete list of what's new.

See you

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to...

The best air conditioner

When readers choose to buy Wirecutter's independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here . After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...
