## DOCKER instructions
|
|
|
|
aggiungere a /etc/host l'entry:
|
|
|

127.0.0.1 cassandra
|
|
|
|
start composer:
|

`docker compose up --build`
|
|
|
|
force recreate docker image
|
|
|
|
`docker compose build --no-cache`
|
|
|
|
check status:
|
|
`docker exec -it cassandra1 nodetool status`
|
|
|
|
## import db
|
|
|
|
`./dump.sh`
|
|
|
|
`docker compose up --build`
|
|
|
|
attendere che tutto sia pronto e i db siano sincronizzati
|
|
|
|
TODO: definire esattamente come, tendenzialmente con nodetool status , nodetool gossip, etc
|
|
|
|
eseguire uno dopo l'altro, quando sono terminati
|
|
```sh
|
|
docker exec -it cassandra1 /scripts/setup.sh
|
|
docker exec -it cassandra2 /scripts/setup.sh
|
|
docker exec -it cassandra3 /scripts/setup.sh
|
|
```
|
|
|
|
flush before switch off
|
|
|
|
```sh
|
|
docker exec -it cassandra1 nodetool flush
|
|
docker exec -it cassandra1 nodetool flush
|
|
docker exec -it cassandra1 nodetool flush
|
|
```
|
|
|
|
run a single service:
|
|
* cassandra1: `docker compose up cassandra1 --build`
|
|
* cassandra2: `docker compose up cassandra2 --build`
|
|
* ,...
|
|
|
|
cqlsh client:
|
|
`docker exec -it cassandra1 cqlsh cassandra1 -k dev_keyspace_1`
|
|
|
|
open bash on server
|
|
|
|
* cassandra1: `docker exec -it cassandra1 bin/bash`
|
|
* cassandra2: `docker exec -it cassandra2 /bin/bash`
|
|
* cassandra3: `docker exec -it cassandra3 /bin/bash`
|
|
|
|
## check cassandra status
|
|
|
|
Check status
|
|
`nodetool status`
|
|
