We are pleased to announce the release of OSv 0.13 Alpha Release. Some of the noteworthy new features and improvements below.
This mean you can now run any NodeJS application on top of OSv for a minimal OS+runtime solution. See a simple example here. NodeJS is available as Capstan base image.
- New example of using New Relic agent with a Java app here
We are continuously extending REST API coverage Latest additions are:
- a new reboot API, os/reboot
- ifconfig to return MAC address, network/ifconfig
Up to date API spec is here
Starting from this release the Lua CLI is becoming the default in our stand alone image. The new CLI can run either on OSv VM (for local VM) or externally (for both local and cloud deployment). On both cases, the CLI communicate with OSv VM over REST API and is subjected to its security (like SSL).
Running external CLI have the following advantage:
- No need to build the CLI into the image in advance
- Using the CLI in combination with your familiar host tools.
For example,
lsis a guest tool,grepis a host tool:
./cli --api=http://192.168.122.89:8000 -- ls -l | grep so
Backtrace data generated by the OSv tracing and profiling tools now include symbol information on Java JIT code as well as exported dynamic library functions.
Images of the new release are available at osv.io/downloads and using capstan search
EC2 community AMI are available here
