Commands

compare

Compare indexes from a target MongoDB instance with a recommended dump.

All logs are written to the STDERR stream, so they can be easily separated from the actual output, which is written to STDOUT.

We recommend redirecting the output of compare command to JSON file.

[!IMPORTANT] The credentials under which the command is run must have read access to all databases controlled by Codefresh.

Options:
  -p, --product <product>                       Codefresh product: classic | gitops
  -u, --uri <uri>                               MongoDB URI
  -m --db-map [dump-db-name=target-db-name...]  Map the databases in the dump with the target databases. We have our own naming convention for the production databases, but it is up to the customers to name their databases (default: ["google_production=codefresh","chart-manager=charts-manager","kubernetes-monitor=k8s-monitor"])
  -h, --help                                    display help for command

Example:

docker run quay.io/codefresh/index-alignment:<version> compare --product "classic" --uri "<db-uri>" > classic-diff.json

docker run quay.io/codefresh/index-alignment:<version> compare --product "gitops" --uri "<db-uri>" > gitops-diff.json

stats

Get stats for all collections from a MongoDB instance. Following commands will be executed:

• dbStats command (doc);

• $collStats aggregation (doc);

• $planCacheStats aggregation (doc);

• queries _id of the oldest doc in each collection.

[!IMPORTANT] The credentials under which the command is run must have permissions to execute the commands specified above.

All logs are written to the STDERR stream, so they can be easily separated from the actual output, which is written to STDOUT.

We recommend redirecting the output of stats command to JSON file.

Options:
  -u, --uri <uri>  MongoDB URI
  -h, --help       display help for command

Example:

docker run quay.io/codefresh/index-alignment:<version> stats --uri "<db-uri>" > db-stats.json

sync

[!CAUTION] This command changes indexes in the target DB, which may have performance impact.

We strongly advice to NOT use this command against production DB because of possible performance impact. Instead, use compare command to get the diff, then consider eliminating index diff manually during maintainance window.

Sync indexes from a recommended dump with a target MongoDB instance. The command will fail if it is required to create indexes on heavily populated collections and the --force flag has not been specified

Options:
  -p, --product <product>                       Codefresh product: classic | gitops
  -u, --uri <uri>                               MongoDB URI
  -f --force                                    Create indexes even on heavily populated collections, which may take a while
  -m --db-map [dump-db-name=target-db-name...]  Map the databases in the dump with the target databases. We have our own naming convention for the production databases, but it is up to the customers to name their databases (default: ["google_production=codefresh","chart-manager=charts-manager","kubernetes-monitor=k8s-monitor"])
  -h, --help                                    display help for command
