Mac ARM x64 image

[dizer]

So when I try to build an image on M1 mac:

# Dockerfile
FROM wnameless/oracle-xe-11g-r2
ADD db/setup_oracle.sql /docker-entrypoint-initdb.d/

I have an error:

Probably the problem is WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested. Any chance to make it works on M1 Macs?

I also have the same problem

Hi, did you find something about this? 😓

Unfortunately not. Happy to have oracle behind.

"ORA-12547: TNS:lost contact" usually means that the server process has died, in this case the installation would have failed and there will be more information in a logfile somewhere. I'd suggest to try it with Oracle XE 21c, e.g. https://hub.docker.com/r/gvenzl/oracle-xe.
I don't have a M1 Mac yet - just curious to know if Oracle would work on it. There will be no native linux/arm64 image of Oracle database anytime soon I guess...

Sadly, that image doesn't work either. Returns the same error.

I was able to run this image on x64 vm on M1.
But this solution is slooow.

[hal9ccc]

Wow, but that is great news anyway! How long did it take to run for the first time? On an Intel MBP 2019 I'd say it takes roughly 5-10 minutes until the database is ready. A more precise way to measure i/o performance would be using DBMS_RESOURCE_MANAGER as described here: - I'm getting max IOPS of 65000, latency 2 ms and max MB/s of 3200 - so nearly raw performance (using Parallels and Boot2Docker)

I think the longest time was to decompress docker image :)
It was around 5-10 minutes.
I created VM using lima with x86_64 arch with docker-ce. And run this image.
On second run it takes 2-3 minutes to run my automated tests on Oracle. So not so bad.

[hal9ccc]

yeah, I've heard lima is pretty good 👍! Would still be interesting to know the key I/O metrics
