## Previous Steps Before Starting

There are many cases where you want to perform some steps **before starting** your application.

For example, you might want to run **database migrations**.

But in most cases, you will want to perform these steps only **once**.

So, you will want to have a **single process** to perform those **previous steps**, before starting the application.

            if (!job.isUnscheduled()) {
                if (StringUtil.isNotBlank(scheduledJob.getCronExpression())) {
                    logger.info("Starting Job {}:{}", id, scheduledJob.getName());
                    final String cronExpression = scheduledJob.getCronExpression();
                    job.reschedule(cronExpression, op -> op.changeNoticeLogToDebug().params(paramsOp));
                } else {

    String[] in = new String[0];
    String[] empty = ObjectArrays.newArray(in, 0);
    assertThat(empty).isEmpty();
  }

  public void testNewArray_fromArray_Nonempty() {
    String[] array = ObjectArrays.newArray(new String[0], 2);
    assertEquals(String[].class, array.getClass());
    assertThat(array).hasLength(2);
    assertNull(array[0]);
  }

  public void testNewArray_fromArray_OfArray() {

      tags:
        - key: name
          value: pick* # match objects with tag 'name', all values starting with 'pick'
      metadata:
        - key: content-type
          value: image/* # match objects with 'content-type', all values starting with 'image/'
      size:
        lessThan: "10MiB" # match objects with size less than this value (e.g. 10MiB)

### Single Container

If you have a simple setup, with a **single container** that then starts multiple **worker processes** (or also just one process), then you could run those previous steps in the same container, right before starting the process with the app. The official Docker image supports this internally.

Let's check back those deployment concepts from before:

* Security - HTTPS
* Running on startup
* Restarts
* **Replication (the number of processes running)**
* Memory
* Previous steps before starting

Up to this point, with all the tutorials in the docs, you have probably been running a **server program** like Uvicorn, running a **single process**.

            if (logger.isDebugEnabled()) {
                logger.debug("Starting Job {}. scriptType: {}, script: {}", id, scriptType, script);
            } else if (scheduledJob.isLoggingEnabled() && logger.isInfoEnabled()) {
                logger.info("Starting Job {}.", id);
            }

            final Object ret = jobExecutor.execute(Constants.DEFAULT_SCRIPT, script);
