Cannot Create A1 Instances on Oracle Cloud Free Tier? A Full Guide to Troubleshooting (Part 1)
🎯 Target Audience
- People who are trying to create an A1 (Arm-based) instance on Oracle Cloud's Free Tier.
- People who have hit a wall because they cannot create an A1 instance.
- People looking for ways to bypass restrictions or find alternatives.
⚠️ Conclusion: Being fixated on "Free" can be surprisingly painful
A1 instances are extremely popular, and the Tokyo region consistently displays the error "Out of host capacity." Furthermore, there is a constraint where free accounts cannot request a limit increase from support.
🧭 1. The sequence of events leading to a dead end while trying to create an A1 instance
Tried to create an A1 instance, but... capacity error
When I tried to create an A1 (VM.Standard.A1.Flex) instance from the Oracle Cloud console, the following error appeared:
Out of host capacity for shape VM.Standard.A1.Flex in availability domain AP-TOKYO-1-AD-1
This message appeared every time, and I was unable to create one no matter what I tried.
🧰 2. Could not even reach the form after accessing Support
I tried to navigate to "Request service limit increase" from the Support menu, but...
→ Instead of going to the form, it just automatically redirects to a chat session.
🤖 3. Connecting to a Live Agent via Support chat
I thought the automated response bot would handle it, but since the issue couldn't be resolved, I connected to a "Live agent."
📉 4. Response: Trial accounts cannot request a limit increase
The Live Agent replied with the following:
Limit increase requests are not available for Trial accounts.
On free accounts, only available shapes can be used.
The Home Region cannot be changed.
The choice of Availability Domain also depends on the Home Region.
🔁 5. Conclusion: Give up and use an AMD instance
So, rather than forcing the use of an A1, I decided to set it up using an AMD-based micro instance (VM.Standard.E2.1.Micro) for now.
