As of May 4th, 2021, erlang is not available from macports for the ARM (Apple Silicon) platform.
Docker containers make it super easy to install postgresql and rabbitmq.
The M1 chips have great parallelism, so I'd hope to be able to run docker without noticing the overhead too much.
I could use conda as well, but docker provides the neat docker-compose.yaml that makes it possible to start up and shut down all the services required with a single command.
| // keepDoingSomething will keep trying to doSomething() until either | |
| // we get a result from doSomething() or the timeout expires | |
| func keepDoingSomething() (bool, error) { | |
| timeout := time.After(5 * time.Second) | |
| tick := time.Tick(500 * time.Millisecond) | |
| // Keep trying until we're timed out or got a result or got an error | |
| for { | |
| select { | |
| // Got a timeout! fail with a timeout error | |
| case <-timeout: |
| Backup: | |
| docker exec -t -u postgres your-db-container pg_dumpall -c > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql | |
| Restore: | |
| cat your_dump.sql | docker exec -i your-db-container psql -Upostgres |
You can find the MAC address for LAN1/eth0 (not the BMC MAC) via the SuperMicro IPMI interface by running the following command:
$ ipmitool -U $IPMI_USER -P $IPMI_PASS -H $IPMI_HOST raw 0x30 0x21 | tail -c 18The eth0 MAC address will be output in this format:
00 25 90 f0 be ef
