You can use the beta of the datalabels plugin by installing it like this:

YARN:
yarn add chartjs-plugin-datalabels@next

NPM:
npm i chartjs-plugin-datalabels@next

Live example with chart.js v3:

Chart.register(ChartDataLabels);

var options = {
  type: 'pie',
  data: {
    labels: ['orange', 'blue', 'gray'],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3],
      borderWidth: 1,
      backgroundColor: ['orange', 'blue', 'gray']
    }]
  },
  options: {
    plugins: {
      datalabels: {
        backgroundColor: function(context) {
          return context.dataset.backgroundColor;
        },
        borderColor: 'white',
        borderRadius: 25,
        borderWidth: 3,
        color: 'white',
        font: {
          weight: 'bold'
        },
        padding: 6,


      }
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
