You can reduce build time by simply running Hello everyone, are you using Cloud Build? Cloud Build is Google Cloud’s CI\/CD service. While it has many uses, it’s a powerful tool for building source code, creating container images, and deploying them.<\/p>\n This is the second article in our series of Cloud Build tips. Last time, we showed how you can save a minute of build time just by using This time again, we’ll introduce a method to reduce build time without changing the actual content of the build.<\/p>\n Within a build process, you often use different Docker images for each step. Also, build steps usually have an "order" because the execution of one step often depends on the result of a previous one.<\/p>\n If you look at the Cloud Build details screen, which has a URL format like Within a step, you might see output like this:<\/p>\n This indicates that the Docker image is being downloaded within that step.<\/p>\n Is this "image download" happening in one of the later steps? This is where there’s an inefficiency. While the "content" of the steps must be executed in order because they depend on the results of previous steps, the image downloads can be done "earlier."<\/p>\n Cloud Build has a feature that allows it to "run in parallel" any steps that do not have a defined dependency order. This is explained in detail in Configuring the order of build steps<\/a>.<\/p>\n Each build step can have an Now, if you pre-download the Docker images used in steps B and C in parallel with step A, the execution time of steps B and C should be reduced by the time it would have taken to download their respective images.<\/p>\n If you want to place the ‘Download images’ step earlier in the file, you’ll need to specify If you see the following in your build step log, it indicates that the image has already been downloaded. You’ve successfully saved time.<\/p>\n By adding a For builds with many or complex steps, consider the following:<\/p>\n This technique applies not only to the images specified in the Note: In this article, we introduced a technique to reduce build time in Cloud Build. By pre-downloading the Docker images used in subsequent steps at the beginning of the build process, you can save the image download time for each step. The following points are particularly important:<\/p>\n By using this method, you can reduce build time without changing the content of the build itself. You can expect significant improvements, especially in build processes with many steps.<\/p>\n Cloud Build \u306e\u30ef\u30b6 \u305d\u306e2 English follows Japanese. \u7d50\u8ad6 \u30d3\u30eb\u30c9\u30d7\u30ed\u30bb\u30b9\u306e\u6700\u521d\u306b\u3001\u3068\u306b\u304b\u304f pull \u3060\u3051\u3092\u5b9f\u884c\u3057\u3066\u304a\u304f\u3088\u3046\u306b\u3057\u3066\u304a\u304f\u3068\u3001\u30d3\u30eb\u30c9\u6642\u9593\u304c\u77ed\u7e2e\u3067\u304d\u308b\u3002 \u30d3\u30eb\u30c9\u30b9\u30c6\u30c3\u30d7\u306b […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[27,13],"tags":[],"class_list":["post-590","post","type-post","status-publish","format-standard","hentry","category-cloud-build","category-google-cloud"],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/p4dIdP-9w","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/posts\/590","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/comments?post=590"}],"version-history":[{"count":2,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/posts\/590\/revisions"}],"predecessor-version":[{"id":592,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/posts\/590\/revisions\/592"}],"wp:attachment":[{"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/media?parent=590"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/categories?post=590"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tako.nakano.net\/blog\/wp-json\/wp\/v2\/tags?post=590"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}pull<\/code> \u3060\u3051\u3092\u5b9f\u884c\u3057\u3066\u304a\u304f\u3088\u3046\u306b\u3057\u3066\u304a\u304f\u3068\u3001\u30d3\u30eb\u30c9\u6642\u9593\u304c\u77ed\u7e2e\u3067\u304d\u308b\u3002

Summary<\/h2>\n
pull<\/code> for all necessary images at the very beginning of your build process. The more images that appear in your build steps, the greater the time-saving effect.
\nImages specified in Dockerfile<\/code> can also benefit from this technique.<\/p>\nIntroduction<\/h2>\n

You can also use the waitFor<\/code> property to specify that a step should wait until a step with a specific id<\/code> is completed. If waitFor<\/code> is not specified, a build step will wait for all prior build steps<\/strong> in the build request to complete successfully before running. For example, in the following build configuration file, steps A, B, and C will run sequentially.<\/p>\nsteps:\n- name: foo\n id: A\n- name: bar\n id: B\n- name: baz\n id: C<\/code><\/pre>\nsteps:\n- name: foo\n id: A\n waitFor: ['-'] # Runs in parallel with 'Download images', can be omitted\n- name: bar\n id: B\n- name: baz\n id: C\n- name: 'gcr.io\/cloud-builders\/docker'\n id: 'Download images'\n entrypoint: 'bash'\n args:\n - '-c'\n - |\n # Pulling 'foo' here is optional, as step A will pull it anyway.\n docker pull foo\n docker pull bar\n docker pull baz\n waitFor: ['-'] # Runs in parallel with A<\/code><\/pre>\nwaitFor<\/code> for steps B, C, etc.<\/p>\nAlready have image (with digest): wordpress:php8.2-apache<\/code><\/pre>\n'Download images'<\/code> step at the beginning, you can potentially reduce your build time significantly, depending on the number of images used.

waitFor<\/code> between the image download steps themselves as needed.<\/li>\nname<\/code> field, but also to those in a Dockerfile<\/code>‘s FROM<\/code> instruction. By pulling all the images used in the build steps at the beginning, you can save image download time in subsequent steps.<\/p>\n
\ngcr.io\/cloud-builders\/docker<\/code> is one of the Google Cloud Build official builder images<\/a>, and downloading this image itself does not take any time.<\/p>\nSummary<\/h2>\n
