To start the Ddb for namaste, at the command line enter:
|
|
|
|
java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb -inMemory
|
|
|
|
Note that this command will run Ddb in memory only - when you exit the local db instance, no data will persist.
|
|
|
|
To run the Ddb instance saving data locally to a file, use this command:
|
|
|
|
java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb -dbPath /some/file/path
|
|
|
|
The help file is incorrect - there is no default - if you leave the dbPath option blank, it will throw an error.
|
|
|
|
usage: java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar
|
|
[-port <port-no.>] [-inMemory] [-delayTransientStatuses]
|
|
[-dbPath <path>][-sharedDb] [-cors <allow-list>]
|
|
-cors <arg> Enable CORS support for javascript against a
|
|
specific allow-list list the domains separated
|
|
by , use '*' for public access (default is
|
|
'*')
|
|
-dbPath <path> Specify the location of your database file.
|
|
Default is the current directory.
|
|
-delayTransientStatuses When specified, DynamoDB Local will introduce
|
|
delays to hold various transient table and
|
|
index statuses so that it simulates actual
|
|
service more closely. Currently works only for
|
|
CREATING and DELETING online index statuses.
|
|
-help Display DynamoDB Local usage and options.
|
|
-inMemory When specified, DynamoDB Local will run in
|
|
memory.
|
|
-optimizeDbBeforeStartup Optimize the underlying backing store database
|
|
tables before starting up the server
|
|
-port <port-no.> Specify a port number. Default is 8000
|
|
-sharedDb When specified, DynamoDB Local will use a
|
|
single database instead of separate databases
|
|
for each credential and region. As a result,
|
|
all clients will interact with the same set of
|
|
tables, regardless of their region and
|
|
credential configuration. (Useful for
|
|
interacting with Local through the JS Shell in
|
|
addition to other SDKs)
|
|
|
|
You will also need to configure you aws credentials which is easily done using the "aws configure" command:
|
|
|
|
$ aws configure
|
|
AWS Access Key ID [None]: YOUR-AWS-ACCESS-KEY
|
|
AWS Secret Access Key [None]: YOUR-AWS-SECRET-KEY
|
|
Default region name [None]: us-west-2
|
|
Default output format [None]:
|
|
|
|
Start the local instance of the DynamoDB:
|
|
$ java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb -dbPath /YOUR/FILE/PATH
|
|
|
|
Test the connection by listing the existing tables in the database:
|
|
$ aws dynamodb list-tables --endpoint-url http://localhost:8000
|
|
{
|
|
"TableNames": []
|
|
}
|
|
|
|
|
|
Note that the aws configure will create a directory in $HOME called ".aws/" and in that directory are two files:
|
|
|
|
$ more config
|
|
[default]
|
|
region = us-west-2
|
|
|
|
$ more credentials
|
|
[default]
|
|
aws_secret_access_key = gVADzw1ZEhl0ie1/ktMW+jz/pPKpdrd7Hr+6Tt0w
|
|
aws_access_key_id = AKIAIGBWL4HXBOOFXH5A
